Just did exhaust got a header/dp and full catback all 3" shortly after the car started going into limp mode. its been happening more frequently over the past couple days its to the point i cant keep it out of limp mode for more than 5 mins. Throwing code P2138 and P2122 dont think exaust should cause that checked all connectors at throttle body and pedal they wern't loose also cleaned the throttle body that worked for about 10 min. I need help before i blow my car up.

holy crap, i'd take that in, something unrelated to the exhaust is causing them. That is all I can tell you from the info given. You haven't messed with that stuff in anyway?

richsoucie

and the culprit is which for those of you that dont know is located here now how would i go about fixing this for one there is no chance of even getting anything bigger than my hand in there and the gm service manual emphasises <--(sp?) that when doing a wiring repair the wire must remain the same length

think tank time whatta ya got

troyss

How do you know when the car is in limp mode? Serious question

richsoucie

feels like you got 50 hp and a light that looks like an engine with a down arrow comes on

troyss

So feels like you have NO power at all? Have you taken the battery cable off for a while?

richsoucie

yes that blue wire is the signal wire for app 1

troyss

Is it cut?

richsoucie

yes sir

troyss

Why did you cut it again? Sorry if I missed it

richsoucie

i didnt car started going into limp mode with a dtc for app 1 app2 mismatch

troyss

Ok, so the blue wire is for amp1 and it is cut right? Reconnect it

I see now I was in limp mode in my head . All I can think of is have someone with smaller hands then you get back there and do it. Or did you try getting the wire out threw the other side?

richsoucie

easier said than done it is at the firwall behind a bunch of **** can barley get one hand in there

troyss

can you somehow pull the wire threw?

richsoucie

tried that too its connected to another harness and clipped to the car in about 50 places

gonna try one of these tommorow Posi-Tite- Watertite Connector will let you all know how that goes

damn man, I'd hate to have to tackle that. wire cutters and crimpers might be your best friends for this one.

Good luck and let us know how it goes.

richsoucie

cant get the crimpers in there however i did manage to get the wires stripped had to pull one through to the inside of the car but i got both ends stripped and im gonna use that twist lock connector on it shouldnt be too hard since i can get my hand in there

brickloaf

didnt really read the thread but it really dosent matter how long the wire is...im sure if you cut 2 inches off so you can splice it, it will be just fine...

scottie

How'd it turn out?

richsoucie

the twist lock connector worked great. never used one before but i would highly reccomend them for tight places. and it was easy to put on one handed
