heres the deal....

My engine idles like crap, sounds like its on one rotor and runs pretty bad until 3k. 3k and above its just like before...its perfect...but in 3rd and 4th gear under WOT at about 5.5k it hesitates really bad like its not getting fuel. Fuel cut? my car is stock??

Heres what I've checked so far....

Replaced plugs & wires
Had muffler shop pull apart exhuast and check cats..they are good
Replaced oxygen sensor.
Checked for vac leaks...haven't found one yet.
I get full and good boost intbetween 3-5.5k and in 1rst and 2nd gear, it feels good all the way up to 7k.

What to check next? I would really like any and every idea to check? Could it be the fuel pump???? the fuel filter is fairly new , however I haven't checked it yet, almost seems like fuel pump...

I desperately need any suggestions anyone might have..

My car is an 89 Turbo II

thanks

 

It may be a few things I would start with the fuel filter, its cheep and better safe that sorry, as far as the fuel pump I know that there is also a small filter on the pump itself that also may cause the prob. The best thing to do is to test your fuel presure if you have the resources. Hopefully I was of some help

 

Sorry to hear your having troubles aleady, I know you just got that TII...

Besides this, how do you like it?? Much better than your old NA???
