My car has been going into engine power reduced. I have checked all my clamps, and looked for leaks at my dp and such. I cant even drive without going into this mode, and i dont even have to go into boost. With my tuned ecu in and i try to no lift shift, the car will shake really bad and bog right down. But if i let off quick it will go right away and i can get back on it.

Then i thought it could be my tune so i put my stock ecu back in and it still doesnt want to run right. I no lift shift from 2nd to 3rd and it will go right into that mode. I dont really know what else to do besides put some of my stock parts back on and bring it to the dealer. If any ideas please let me know. I really dont want to bring it to the dealer.

Thanks
Mike

 

Have you tried disconnecting the evap solenoid connector at the intake manifold? Somebody here was having somewhat similar issues and disconnecting it helped him out.

 

it that one of the things that sits right on the top pf the mani.
