Car engine problems need help!
2009 COBALT SS TURBO. MODS: hahn intake, hahn catted downpipe, hahn 3" exhaust, hahn charge pipeing. and the gm stage 1 kit. i havnt dyno tuned it thats probably the reason all this crap is happening. but here is my problems. all the engine codes i have encountered. code: p0036, p0038, p0101, p0106, p0138, p0141, p0236, p0420, p2270. took it into the dealership got them all fixed fixed most of my problems. except the 106 101 236 and the 420. the p0106 whenever my boost guage says no data available that code comes up but its very random. it only stays on for a couple seconds then stays off for weeks. dealership cant fix it cuz its never on. the other three as soon as they came on. all sorts of **** started happening. to start the intake after letting off the gas it makes that noise a semi makes when it shitfs pretty cool means its working normal. now sometimes instead of doing that. it will make adnormal sucking and blowing and it makes that wooshing noise kinda sounds like there is a leak. also when the p0101 came on the car jerks violently sometimes. kinda like a bad tune. and when it does that. i loose power in some of the gears. also my boost has been cut in half. had them check for boost leaks and just any kind of leaks in all the pipes. nothing. had them check all the sensors they said they were all fine and working correctly. i have no ******* clue whats wrong. so now they said its my cat. the car wont reconize it causing all the problems. so im switching it back to the stock downpipe. and after i get back from my deployment next year im dyno tuning it. other than that. if that doesnt fix it then im all out of options. what do you guys think. your input would be appreciated thanks.
