WTF is wrong with my car! *vids* GMSC I need your help!

[CobaltSSTuner]

See this thread here for background story: http://www.gmsportcompact.net/forums...codes-no-start.





The only code the car throws is a p1183 which is the supercharger pressure inlet sensor, however it was shut off via hptuners a while ago. "hard reset" the car, where you pull the ground cable and let the car sit with the positive cable still on the battery, and "supposedly" its suppose to reset the ecu. But I didn't think that it was possible to erase the tune

Only thing i do notice is that when the car does run, it runs HELLA lean, like the car sounds like it is starving for fuel, which is why it runs like ****.

I'm seriously lost. I can't figure out what the hell is wrong with this thing. I've done everything. Any ideas would be super helpful.

[CobaltSSTuner]

Bump!

[USMCFieldMP]

No Impact, No Idea.

how did you get the old P2228 and P0107 to go away? did the P1183 come back after those went away? Baro and SCIP are swappable connections......I know this was mentioned, but just saying it again.

The SCIP sensor should be the one with the green wire in the middle.

[CobaltSSTuner]

The plugs originally got switched so I fixed that and haven't had issues since.

[Maven]

Well you do have an issue if youve got an 1183....

I cant watch the videos becasue PB videos screw with laptop for some reason but whats it doing? surging?

[USMCFieldMP]

but whats it doing? surging?

Bingo.

[Maven]

surging and lean is probably an issue with the SC install. My yellow car was doing that, had a grain of sand on SC gasket.....

[Maven]

get a can of brake clean, and spray it around the supercharger base and intake manifold while its running, if its smooths out its got an air leak there......you can also watch your STFT while doing this they should go negative or at least go lower when you spray near the air leak. Got the big round ring for the bypass in place?

[BLAZIN07SS]

he is turbo swapped

[Maven]

Okay, whatever, swap the word supercharger for supercharger delete plate......as far as I read on the other thread he was running the stock IM......am I wrong?

[USMCFieldMP]

Same principle applies. Vacuum Leak, I'd say. Mine did it pretty bad when I had a Vacuum Leak.

Who tuned you? And on what Injectors?

oh re-read his other thread. he put the stock mani back on. i thought he was on the lk9 mani he had

[CobaltSSTuner]

Ebristol gave me a base tune, nothing wot dome yet. Just daily drivable and some half throttle. 60lbers. It ran fine prior to attempting to switch manifolds. I checked all vaccum lines, and everything is as it shoud be

[CobaltSSTuner]

I have the lk9 mani. Put it on and I had sone issues to work out with it yet. So I put the sc delete kit back on temporarily. And now it won't run for ****.

[USMCFieldMP]

I think you have some leaks. Do what Maven said, and hit it with some Brake Cleaner.

[ThePaul]

yeah seems like a vaccuum leak, or a pinched wire some where

[G85 SS]

And chance of this being an effed throttle body?

[CobaltSSTuner]

^^that was one my thoughts as well.

I will f with it some more when I get home from work. I'll try the brake cleaner and I'll check all my gaskets and such.

Yes.
