Contour Enthusiasts Group Archives Forums General Troubleshooting @#$^&%$........WHY???????

I was real excited when I got may car and the parts I order all put togethier. I did the intake clean, headers, 75mm maf and a new intake, I bought a chip but my computer needs a mod so I have to send it to superchip. When I first got the car I added a pair of flowmasters. and removed the resonator. I didn't like the way it sounded so I put it back in, backwards on the advise from the muffler guy. Its sounded sweet, but now that I have these new parts I think its hurting my car.. I went to the track, and found out some stuff...1. the car is almost 2 seconds slower then before, 2. My clucth is about to retiere. 3. My rev limiter no longer works, when the clutch slipped I hit 8 grand and back fired. My trans feels real smooth now, and the car shakes slightly at idle. My question is ....1 is the resonator clogging me up. 2 Is my computer bad or going bad? I removed it for the chip install and cleaned the contactors, did I do some damage to it?? and the shaken did I damage something? or should I say what did I damage. Should I just go and get some dyno and tune time and make sure that the comp and the mass air are working togethier, and to tweak the a/f. Sorry so long I just wanted to give enough info...Please help.

Put the original chip and MAF back in to verify that you have not introduced any problems into the system.



The chip must be burned using the MAF data sheet to insure A/F is correct. If you want a REV limiter you must tell them, they normally take it out.

I did that and it worked fine, but it still shakes at idle
