Default Injen CAI on MY99, checked Maf, still won't run

I just installed a used Injen CAI on my 99 rs... Install went fine, exceept had to pull the loom over a little bit to have the maf still plugged in, didn't seem like a big deal. Anyways, so I go to start it up, and immediately CEL is on, and the car won't rev over 3500, and won't hold an idle. I triple checked all of the connections, and there aren't any vacuum leaks. The MAF is only like a month old, but I tried swapping it for another, and still no luck. The thing is also acting the same way with the maf completely unplugged. Any suggestions?

Do you know what codes are being set?

how much did you have to move the wire loom, did you stretch it alot?, enough to damage it? Check the connector, are all the pins ok? damaged, pulled out?

Is the maf you swapped in a new maf? or known to be good?

a vacuum leak really wont cause the car to not rev of 3500 rpms, if its acting like the maf is unplugged (rev limititer) I would first be looking at the maf sensor, and or wiring and the codes being set.

Are any of your pcv valves off unplugged? If so, you'll def throw a cel (I threw a blinking cel when one of mine came off after intake install).

Is your MAF backwards? Just a thought if you put the adapter on for the cone. Did you reset your ECU as well?

Maf is on the right way... No vacuum lines off at all, and I just tryed to reset the ECU. Didn't make any difference. I really didn't pull the wires very hard at all, but that's the only thing I can really guess at this point. The MAF was known to be good, because the car war running fine right before I took the stock intake off.

if you replace the stock intake setup and start the car and it works that means that you didnt damage something. just trying to help you narrow down the problem.

I'm going to try that tommorow, If I did screw up the maf wiring somehow, how do I splice a new plug on there?

Ok I've narrowed down my problem a little bit, but it's getting more confusing as I go. I found a couple problems that I took action to correct. One was simple... a plug underneath where the airbox was, now it at least will hold an idle, still limited to 3500.

So I reset ecu again, still nothing, and I'm playing around with some of the wires. I touch the maf wires, and the car dies. Intersting... So upon close inspection, one of the wires was almost completely sheared off from the maf plug. So I pushed the connector out of the plug, and re-soldered it back on, put the plug in, everything seems groovy. I put some electrical contact grease on the connector too, to see if that would help. Now, I plugged it all back in, and It won't run AT ALL with the maf plugged in, but same result as before with it unplugged. I wiped off all the grease, and tried swapping maf's again, still no luck. Any Ideas now?

i think it's time you bring your car to the dealership. When I installed my injen on my 99RS I didn't have to move the MAF. After i installed it my car didn't idle well but after some driving the ECU learned the new mod and ran fine. I also had to plug one of the vacuum holes. Just to warn you now before you drive your car again, the intake sucks up water really easily. I was driving through a tiny rain shower and my engine almost locked up. you should really invest in a by pass valve if you intend to drive your car daily. As for me I'm going to replace my Injen with a cobb tuning one. good luck with your MAF problems they are such a [email protected]

It's going to cost a fortune if I take it into the stealership, as I'm sure they'll want to replace the wiring harness, along with some other things I bet.... It might have to come to that. I just soldered another wire that was kinda suspect, and the problem still persists.

I'm pretty sure it's not a matter of it working stock right now either, but I"m about to try it to see. It's really acting like something else has gone wrong in this whole process...

From my personal experience: Car won't start = blow MAF.
Won't idle = unplugged MAF
Oh, and the INJEN intake works GREAT. I had it on my car for several months; great power, not too loud, drove throught multiple rainstorms and never had a problem with it. You just need to get it installed right.

Uh? How does your engine "almost" hydro lock? That's like saying "My girlfriend is almost pregnant". It either hydro locks or it doesn't, and if it does, you will instantly know about it. It takes a TON of water to hydro lock an engine; you'd have to get your filter under a puddle for that to happen.

i just recently drove through a MASSIVE rain storm, it was wipers on warp speed holy crap i just hydroplaned kind of storm. i have basically a tube off the airbox going into the fender. only filter i have is the K&N panel in the airbox. the car was absolutely fine after driving for about an hour. then i arrived at my destination and checked the tubing out. it was "moist" on the inside. car ran beautifully.
