Ok today.. I installed STILLEN Race pipes.. along with my DRYFLOW Filter for them AEM CAI right.. well everything went well I started the car raised it on the lift no leaks it was great so I drove back home and It was all good. I was so happy that I decided to go out and drive so I found myself on this nice str8, no cars.. so I let it rip but as soon as I hit 4K rpm the engine wont respond to the throttle as if no fuel was being fed..the engine wont shut off be beyong 4K no thing happens.. I let off again and press just below and it goes up again. I've been thinking but I am not sure maybe I am lean or rich.. I dnt know what lean or rich means but I think is one of those 2 as I heard this happens when you do alot of exhaust mods. I have headers, TP, Y-pipe and the exhaust.. my CEL is on.. so i guess something must not be right.. oh yeah I have some mean poping sound.. might be backfire but not really..lol Help me out..

 

CEL is on because you don't have any cats, your 02 sensors are reading the same in the first and second banks. Could be a MAF sensor problem. Did you start the car without the MAF sensor in place? Or maybe damage it in some way...

 

CEL doesn't always come on because of test pipes. I've had cars with them installed and been running for 6+months without a light coming on. Some after a week. Most the older Zs (03-05)dont seem to have a problem the 06 models seem more sensitive. Anyways if you bring your car to sonics I can scan it and see what it says. More than likely if your car is doing that. Thats the cause of the light.
