DAMN AUTO CARS. Anyhow, here's my problem. Ever since I got the car back together it's been running funny when cold, jerking (violently) from 2-1 d/s. When it warms up it runs a little better, but the shift problem stays. I put a set of injectors in it, and it's acting like it has a vacuum leak. I just went over the whole vacuum system (except for the res., which I can't get to now) and I have no leaks. One thing that started yesterday (which really sux) when ever I go under heavy boost (9-10 psi) my vac. hose to the booster pops off :shock: :x ChisA (I think) or whomever has done a vac. swap, how did you keep the booster hose on?? I never had problems until yesterday. A few weeks ago I had to drive to work w/o ANY vacuum lines hooked up in the Cutty, so I know how it feels to drive w/ no vac. on the MAP sensor, or the fuel reg. That is EXACTLY what the driveability problem feels like. You have to stab the pedal to get it to go or it'll bog down. Here's the odd thing, when the vac. line pops off the booster, I DON'T GET A SES LIGHT. :?: :?: My light lights up upon test w/ the KO/EO. So why no SES light? As I said, when it warms up the problem all but disappears, but it's still there, ever so slightly. But WHY does it go away, what vacuum leak do I have that goes away w/ engine temp.? I thought manifold, but I checked my bolts, all tight, and I'm just lost altogether. I did get to race and beat a I6 Wrangler though. I'm only getting 18 MPG, ~~~~, If I can't at least get it upto 20, I'm gonna have to go back to the Gutless, which I don't wanna do when it's warm out, and I can peel that sunroof back. 8) Many thanks for whatever help I can get.
