Unhappy My new car wont run, possibly not all cylinders working???

Hi everyone,
I need help! I just bought my car yesterday (used) and when i was driving home I got a CEL for cylinder 2 misfire. I cleared it, and it popped up again. My car started hesitating a lot then I parked in my driveway and turned it off. Now, when I start it it will start up good, but then it cant idle at all. It will just kind of gurgle and then if I dont hit the gas it will fall to almost 0 RPM and then die. If i hit the gas, a few seconds after it will gurgle up to about 2K RPMS and keep going back and forth between about 300-2000, as soon as I let off it dies shortly after. I am running TurboXS stage 4 with FMIC...I tried changing the coil pack on cylinder 2 but that didnt work. Then I got a CEL PO113, intake temp sensor high input. I have an AEM intake, so I pulled the MAF and cleaned it up with some alcohol, and that CEL hasnt come back after doing that after I cleared it. So...just now I started it and it sort of stayed alive for a couple seconds so I went to look at the engine and I heard some loud ticking intermittently coming from the passenger side of the motor. I pulled the plugs and they look good, I am pretty sure they are sparking but I am going to check that in a few minutes. What else am I forgetting? What is that ticking noise??? My Utec shows no signs of knocking when I hyperlink it...any help would be appreciated greatly! Thanks
Josh

That's like the worst intake repoted on here. Aside from removing intake(put stock box or shorty intake), have a compression test performed. If when you swap coilpacks and the mis fire doesn't move with it. It may be a big problem. Your info says you own a 00RS. What year WRX did you buy and did you play with the utec at all? IE alter any maps the previous owner made.

OK,
pulled the MAF harness out from the top of the intake, and unplugged the UTEC, leaving only my stock ECU, and the car will idle and run fine. I am a little skeptical to drive it, but it sounds fine when revving it lightly. No more unburned gas smell, but of course I got like 5 CEL's for my MAF missing. SOOO...I guess I should replace the MAF and try the UTEC again?? What do you all think keeping in mind the MAF is $300. I dont have the stock intake...and I dont think one will fit under my aps intercooler piping, but should I try to do something about the AEm intake?
Thanks!

Do the comp. check, unplug the utec till you know what your doing with it. The intake has been known to case maf problems but what you have sounds worse then just a little intake playing games with the maf problems. Did the ticking sound like marbles bounceing around in a tin can?

When the car idles and revs (utec unplugged and MAF unplugged) I hear nothing like detonation...the clicking sound was actually only at low RPMS (under 2500) when the utec was plugged in and the MAF was plugged in. I really hope its just the blown MAF and the Utec just doesnt have any way to compensate for the blown MAF while the stock ECU can compensate to at lleast make the car run ok. So, if I get a replacement MAF ans everything works even with the Utec plugged in, should I immediately get the MAF on a different intake? Can anyone confirm if the stock intake system will fit under intercooler piping? Thanks for the responses!

You cant use the stock system with a front mount... you have to use a shorty. Do the comp check before you buy the maf.

Ok, Ill do the comp check tomorrow morning. I want to get a shorty intake, but my car came with the AEM intake which loses the plastic flex pipe part of the intake so i dont have that part. I think I can only run a CAI with the setup i have now and only a couple of them will work with that plastic piece...

The intake isnt going to be that big of a deal... so dont worry about it.

Make sure the connectors on all your coil packs are completely seated, and the coil pack is on the plug properly. One possible explination for the low rpm ticking is a coil pack that is sparking to ground, instead of through the plug.

Update:
With the Utec and MAF unplugged, the car runs, and well. Although, I hit WOT for a second to see how it reacted and it hesistated VERY hard and I immediately backed off so I think up to a certain point the facotry ECU is doing well compensating for no MAF (ie, under 8 psi) and anything over that it has no idea how to compensate for fuel and such so it hesitates really badly. I'm going to check all my connections and such and make sure everything is in order, but since its running WELL, it cant be bad compression or missing a cylinder. I even took the brand new coil pack off and it ran the same, so I am returning that thanks to a nice parts department (john elway south). They have the MAF in stock so I am going to pick one up on Monday and hope that is the cure. Cross your fingers for me...and thanks for the responses!

I keep forgetting to add things...are there any other opinions on the AEM intake out there? I am very limited in options as the fmic pipes are huge and invasive, but I dont want to blow through another $300 MAF in a day because of that damn intake. I plan on at least replacing it with the APS CAI at some point in the future, but how imperative is that? Should I drive easy until I get a new intake assuming everything works again with the new MAF?

An intake isnt going to kill the maf.... it may play tricks with it but it wont brake, hurt it or anything like that. Isnt the aps a stupid amount of money? Dont waste money on things like that get the blitz SUS.

Default MAF

Since you took the MAF sensor off I just thought to mention, it is possible to put the MAF sensor in backwards. The plug on the MAF should face forward.

Tried to switch direction of the MAF, but it doesnt line up correctly the other way, and the intake pipe is going in the right direction....however the plug is facing towards the firewall (that is, the plug female end on the MAF)

Hello,


I had two main problems with my car in which the car would not start or drive at all:

1: If you change the position of the MAF the car would not start or drive even though the MAF can be bolted either way.
2:If you Blow off valve gets stuck open. Mine got stuck open because I used some type of oil tlo lubricate it and the piston walls got really dirty and sticky resulting in stuck piston(specially if you have the Blow off valve running with the stock spring and no spacers which makes the spring to not have enough power to go back to original position(Turbo Xs BlOW- OFF valve).

I hope that this helps. Good luck!!

I'M GOING THROUGH THE SAME THING!

begins last saturday

just flashed to 4.1, tried OLF with stg2new TXS basemap, drove 15 miles pretty easy on it, began misfiring badly at idle, tow to shop, plug #1 was fouled badly with fuel, others were ok... compression was 140/165/165/165, replaced plugs and moved coil packs around

100 miles later began missing badly again after it had been driving great, pulled plugs again, now it's #4, ordered a used coil from ron @ axis racing... installed and cleaned up plug, reset ecu, cleaned maf (1.2v @ warm idle here in 30f michigan, stock airbox/paper filter)

drove another 100 miles till this saturday, once again had been driving great, BAM misfire again, this time with a constant or flashing CEL right from start though, also dumping fuel out of hte muffler like a smokescreen like the last two times this happened (YES I SAID FUEL, NOT COOLANT)... pulled codes, cyl4 misfire (has different coil now) and bank 1 too lean.... reset ECU again to get it to barely run well enough to put around (runs way too rich @ idle, utec shows weird IDC Values from 6%-50% cold idle, missing badly still)... finally get frustrated and shut the car down, pull battery cable again and uninstall utec... PRESTO fires right up without a glitch, runs rough for about 4-5 seconds and now all is fine, drove it 50 miles

do we have bad UTEC's? i'm out of ideas and have been trying to figure this one out all week!

P.S. during this time i've also tried to switch between OLF on and off, makes no difference, shows 20in/hg of vacuum at warm idle no accessories and running condition/power output is great when what i think the intermittately bad utec is working properly... no oil or coolant loss and when it isn't misfiring (seems to be a 100 mile interval this happens) everything is PERFECT

I realize TurboXS goes through great amounts of beta testing and testing on new software updates but it just seems like there's a flood of mis-running cars since the software release, could be coinscidence... i'm not bad mouthing TXS here, my car sucks without it... just a little concerned, maybe there is a software issue surfacing here, maybe we have hardware issues (mine's a rev 5 with 2 toggle switches) or maybe UTEC isn't involved at all... just REALLY REALLY seems it is at this point

Replacing the MAF today and resetting the ECU...we'll see what happens. If that doesnt work I will have to check the uppipe :sigh:. If that it isnt it, I will bring it to the shop. I dont know that its the Utec, because with mine at least, it runs the same ****ty way with the utec plugged in as with it unplugged as long as the MAF sensor is plugged in. This sucks...I want my new car to run!!!!!!!!!!

Have you tried with MAF plugged in and no UTEC? When the MAF sensor is unplugged the computer goes in to a limp mode, which isn't very good at anything other then limp. Also it's very possible that the pipe that holds the MAF is backwards. This would explain why your sensor is facing in the wrong direction.
