How do the plugs and wires look? I had the same problem with my step 2 iridium plugs and were gapped improperly and ruined

well i changed out the plugs with another set, and it didnt fix the issue..

Adionik · 07-10-2009, 07:21 PM

That is a very weird problem indeed

I think I may be having this issue with my stage 2 car. I've done all the tests(vacuum leak/boost/Sensor voltage,etc...) and nothing seems to be wrong. I have no engine light, but if at idle I am running a 13.7-14.0 a/f ratio and it stumbles a little. Then if I go WOT the car falls on its face completely. I am only boosting 14psi now to see if that would help, but NOPE!! Also I boost leak tested the car up to 22psi and no leaks were found.

The worst part about this is my car was running 12's at the track last year and now with this whole "hitting a wall" crap I am running 14's...worse than I did stock!!

I'm am about to replace the TPS sensor as well, but I think I'm gonna wait for your answer. Please hurry.....

figure out this shat mang

isthatguy · 07-15-2009, 09:51 PM

trying too, this weekend i will have more time on my ahnds, and the car is getting dropped of at adams to do some sensor swaps!

kenoshasrt · 07-15-2009, 11:17 PM

I'll be awaiting your results.

tps = no fix

kenoshasrt · 07-18-2009, 05:22 PM

Well yesterday I changed the TPS sensor and like you - no fix even after 50 miles of pcm relearn time. Then I decided to throw on a different WGA that I had and BAMM(set to 20-21 spike/15-16 hold with the bleeder valve), and the car was pulling like a freight train again.

I never thought to change my WGA because the boost gauge would read up to a 20psi spike and hold 14-16, but I guess something was messed up with my Kinetic WGA. If you have another WGA to try it couldnt hurt

Just remember to reset the pcm(pull fuse and disconnect battery) after the install and dont race the engine for atleast the first 10 miles of the test drive after install. Otherwise the pcm will pull timing like crazy because its trying to relearn base maps.

i got my issue resolved, it ended up being bad MSD plug wires.

kenoshasrt · 07-19-2009, 01:52 PM

You know what, now that I think about it I did change my MSD wires out for some Stock ones at the same time as replacing the WGA.......

F*CKING MSD!!!!!!
