Thanks for your advice. I ran that Jectron (spelling?) cleaner through the car three times and that didnt seem to make any difference. It seems to me that the problem lies within a sensor. If you open the throttle when its cold it hesitates for maybe a second or two then runs fine. Then if you let it drop back down to idle and do it again it does the same thing, even after it drank some fuel. The problem is definately temp. related. Should I continue running cleaner through the system? What sensor could the problem be? I don't know much about those Bosch systems and they seem to be a little more complex than most. Coolant temp, thermo-time, AMM, cold-start valve? Thanks a lot.
