hi everybody, I posted the other day on this car with no response...The plot thickens... My 93 bonneville se has several of us here totally bafffled...Just replaced the engine with a low mile used one..engine sounds great...Here's the problem. ..The car runs horrible for the first few minutes on a cold engine...it idles around 2000rpm and nearly dies when you try to accellerate..once running approx 2 minutes, it's drivable but has a hesitation from a dead start. Once your moving it runs pretty well. The check engine light is on intermittantly and was initially producing a different code every time I scanned it. Thinking at this point that I had a bad computer, I replaced the computer. Light's still on and off, problem's still there but now the only code info I'm getting is "fault in ESC circuit" and my scanner shows 0 deg timing advance...sometimes? New development I think may be related----Now the engine temp guage will not reach more than 150 deg f.---Replaced thermostat...again...no change, stll says it's not warming up fully, but I think it really is...{good heat, fans cycling properly} I'm beginning to suspect a bad ground problem somewhere as I have had a few other wiring problems crop up with the pwr windows and seats which required running a new grond wire to correct. Has anyone seen a problem like this and any suggestions where to look? thanks to all Gonz
