2.3l falls bogs when hitting boost June 22, 2009, 07:51:10 AM Hello, im new to the forum. I am pretty mechanically inclined but i cannot for the life of me figure out why my 1988 turbocoupe falls flat on its face the very moment it hits boost around 4k rpms. there are no obsrtuctions in the air tubing, basically every electrical ignition component (accept the ecu) have been replaced. i bought the vehicle with this problem and it continues to plague me. any help on my next direction? Thanks! Quote Selected

If you can grab it and close it easily with your hand, and it doesn't feel like there's the support wire in there, then it needs to be addressed. It's a very common thing. Quote Selected
2.3l falls bogs when hitting boost Reply #5 – June 23, 2009, 10:14:54 AM well to my suprise i found the problem, of course looking me right in the face the coupling that joins the intercooler to the tb was not seated properly. i had to adjust the bracket to the intercooler, reattatch them together and wow what a difference. all i had to do was open my eyes! the previous owner has put over 1k worth of labor and parts into the vehicle to try and figure this out! should i call him and tell him what the problem was? THANKS AGAIN for the suggestions to repair my issue, i probably wouldnt have noticed it this soon if i didnt check the hoses! Quote Selected
