Alright I'm headed out to get it now. Thanks man

 

Alright I got it and sprayed it it's all clean should I spray inside the cable also... ?

 

I can't get the bottom map sensor off its a pain. Any ideas...

 

Yes it is a bitch to get to, If all else fails, try loosening the lower CP hose clamps so you can wiggle it for better access. Proper tools are key though. Should be able to reach it from above.
And no need to spray any cables

 

I can reach it from above. I just can't turn the bolt it's super hard.. I'll try to loosen it thanks for the tip. I just don't wanna strip the bolt

 

Cleaned both of my map sensors still having the same problem. I think I need a Re tune stupid trifecta.. Anyone have a solution?

 

I'm going to say this again. TUNES DO NOT JUST GO BAD

You have a connection issue or a sensor.

 

I've checked everything. I have 10 cel lights on all for air flow. .. I don't understand.

 

List all the codes even pending codes

 

I didn't get them most of them are p0 codes.. P0101. I don't remember them all. One said turbo underboost all the others were for air flow

 

Boost leak club is about to drop the hammer on this thread.

Did you hit a raccoon recently?

 

I haven't hit anything. I've ran several boost leak tests took it to a mechanic to see if they could fix it told them what wrong with it and everything..And nothing they ran boost leak test also and found nothing. I just don't get it cause when I start the car I have full boost and everything until about 30 seconds then It's like 3 lbs.. Then I shut if off while rolling drop the clutch I get boost again then nothing it's really weird. No holes in fmic no leaks new Maf cleaned map sensors tighted all couplings around all charge pipes. Only thing I have Is a exhaust leak which is by the muffler... I'm stumped.

 

Well a p0101 is some type of air meter issue. So you know the problem is between the intake all the way to the throttle body. Will need to check every sensor and every connection. mAF, intake, charge pipes, Map sensors, intercooler.

And this is were the codes come in, the more codes you have OP the more we can narrow in on the potential issue. Generally the P0101 points to a boost leak and not an actual MAF sensor issue. If you have a friend near by with a LNF swap out MAF sensors and see what happens, or keep driving around until the codes set again

 

I've checked all of me them. Nothing on the throttle body though... I'll get all the codes tomorrow so hopefully you guys can help me out

 

Did you check your fuses?

 

No... What fuses would I check...

 

Which MAP sensors do you have? Stock or the GMS1s?

Also you could have something wrong with the wiring going to the MAF. The MAF could be working perfectly fine but if the signals aren't getting to the computer its going to jack things up.

 

 

Gms1. How would I check if the wiring is bad.. Take it to a Chevy dealership?..

 

You can either do that or trace the wiring and see if you can find anything bad. Only thing is dealership is going to hit you with a $100+ "diagnostic fee" ...but they'll tell you what is wrong

 

Alrighty so I'm checking the map sensor wires and the Maf wires... Only thing is how do you know what's bad..

 

Just check all the small ones in the fuse box under the hood. Just to rule out that the codes are caused by one or more sensors not being powered. I had 7 different codes once and turned out to be one damn fuse.

 

Did the fuse effect your boost though..?
