Default I/M Cat and Evap not ready after 350 miles.

I was having trouble passing emissions because of a misfire issue. I think i have that squared away but i can't get my Cat and Evap system to go to ready. Here in Utah we can have one not ready and pass so i just need one to change. I have the drive cycle for my car and have done it a few times but they still won't go to ready status even after 350 miles this weekend with mixed city and highway miles. Does anyone anyone know if there could be something else wrong that would not cause a code to be thrown but would still prevent my IM readiness from going to ready?

Put more miles on it or force pass readiness.

I've been driving it nearly everyday for 2 weeks. It's past due now so i don't want to drive it forever if there really was a problem and it's never going to go to ready. How do you force readiness? I don't think it's an option on a 04 rs. I'm tuned with a PP6 piggy back since that's about the only option for the 04 rs, 05+ you can do open source.

You need to read all the codes.

My reader says 0 codes and faults. That's what i was wondering. Is it possible that there is something wrong with my evap system and not get a code?

evap is impossible to get ready on almost every car. Takes a while to get ready for some reason, even if you force a ready.

Does you state let you pass with 1 not ready?
I just passed my emissions and my results actually said my Evap was not ready. But I live in a state that lets you go with 1 not ready.

look for the exact cycle online... basically, drive exactly 55 for a while (iirc), and do plenty of stops and starts...

...or force pass readiness as said.

I've got the exact drive cycle, I've had issues passing emissions for the last 3 years ever since i installed cams and a LW Flywheel. I just did a trans swap and put in the heavier sti flywheel to get rid of the misfire codes and it worked except for cylinder 2. I ended up going through new plugs, adjusting the lash a couple of times, injector cleaner and a new rear 02 sensor before it finally went away. But now I've been driving it for weeks and it's not going to ready. I guess I'll look into why my cat is not ready yet, after researching it will be easier than tracking down something in the evap system.

as far as i know they dont' make a tactrix cable for my car. On thier web site they said is's not compatible. I've heard that ecuexplorer might work with a vag com cable for a VW, i'm not sure if you can force readiness with it. It hasn't been confirmed to work on my year, only on a few of the older years and the 05+ but they can also be open sourced tuned. I'll look into it further and keep driving, 390 miles and 30+ drives and still not ready.

does your car have any sort of 'rear o2 sensor wired in fix'

if so...that must be removed

and if you google 'obdII drive cycle" and see what some of them involve---the Ford one comes up...and you drive specffically to replicate that cycle and it still isnt 'ready'

then you have another issue somewhere

I have delta cams and a lw crank pulley and a lw flywheel. They are known to cause misfires with all three so i would have to delete the misfire codes and do the drive cycle and hurry and get the emissions test done before the code came on. I later installed 6-speed so i used the stock sti flywheel hoping that going from a 11lb fly wheel to a 18 that would solve my misfire issue. It helped but i still go them on occasion so i hadn't been worried about it until it was time for emissions again and the misfire codes started coming on quick, so i figured i might really have a misfire now and it wasn't just the cams. I replace spark plugs, rear 02, did fuel injector cleaner and adjusted the valve lash and did a leak down test. The misfires stopped but the i/m readiness is still not ready even after doing the drive cycle and driving it for at least 3 weeks since i reset it.

I was looking into the evap system since I will get codes for my exhaust. I had the wire fix for the rear 02 but took it out when i put in new rear 02. I have a spacer in it now but I will take out and see if that will allow it to go to ready with out getting the p0420 or p0137-9 codes. I was hoping that the evap would go to ready so i could pass but after researching for over a month now i was starting to think that there might be another issue that is causing it to not allowing everything to go to ready. I know you can get a codes for certain things if there is a issue the evap system but could there be something that i wouldn't get a code for and could cause the I/M status to not go to ready? I'

oh boi.....and you wanna pass an obdII check with all THAT

leave the spacer in the rear o2....the wired in ones are the trouble makers

I see no way other than forcing readiness or getting somebody with a select monitor to figure it all out

^haha, i posted that up for someone about 2 months ago. That is a generic drive cycle, i also have the exact one for my car, it's similar but doesn't require the a/c and defrost. So over 600 miles and still not ready. I unplugged my battery last night to start over so see if resetting the ecu might help. a reboot seems to fix about everything so i thought i would try that. Anyone else have any ideas?

if you drove the obdII cycle and it still was not ready.....you need some sort of scanner that will tell you which tests are incomplete and then address those

you have some issue that the ecu isnt throwing a code for but is still unready


you will not solve this without some way of seeing what is going on in the obd process

Old thread but I just want to say for any that use Torque they have that feature in, I cleared the EGR part today which was pretty easy once I figured out how to clear it
