Message :"Also when just driving at a consistent speed on the highway, not
:removing my foot from the gas, the car will just stop accellerating, as if I
:took my foot off the gas completely. To get it working again I take my
:foot off the pedal, and than press it again, and its all real jerky and
:hesitant ."
:I had this exact issue. I tried so many different things, I datalogged to
:see which sensor was out of whack and I couldn't come up with anything.
:I finally switched out the ECU and the problem was resolved. I don't
:know for sure what the issue was with the ECU, but my best guess is that
:something inside got messed with when I hooked an emulator up to it. I
:think the ribbon probably bent or broke something inside the ECU
:causing my problems. If you know someone with an extra ECU (or
:borrow one from someone's car to test it) you could see if it fixes your
:problem.

i have not been playing with the ecu lately and also do not have anybody to swap with for a second. I am starting to doubt it might be a vacuum leak...but i am going to test in the shop this weekend.

I removed my passenger side air intake that goes to the plenum. There was a connector hidden down there, that when removed the car would crank but not start... I removed this connector which was stuck because of corrosion. It was really green, both sides of the connectors. I scrapped them and added dielectric grease but have not noticed any performance difference..

anyone else get this hesitation problem??
