1. I have a 1988 Ford Taurus GL wagon a 3.8L engine
2. 90,000 miles.
3. Automatic transmission
4. Front wheel drive
5. No strange sounds
6. A power steering fluid leak
7. Regular maintenence always done on time, it has blown its head gasket at around 40,000 miles (replaced) and I also had the heater core replaced last summer, which required removal of the entire dashboard.
My taurus hasn't always had a perfect idle - but about 6 months ago it started to get a bit rough. I didnt really think anything of it since everything else was fine. But for the last 2 weeks, the idle has been extremely rough, especially upon startup and the car will occasionally stall. The bigger problem, however, is that the car will hesitate violently after I get going under any type of acceleration. This will continue until I reach approximately 20 mph, at which point I can press the accelerator pedal halfway down and it will instantly surge back to life. I usually dont have problems after this - it will idle okay (just okay) and I will only occasionally have to deal with the hesitation after stopping at a traffic signal. Also, I can feel the car not running quite as smoothly as it used to at low RPM's on the highway, on an open road, etc.
I cleaned the IAC valve but that didn't get me much. I thought this might be a vacuum leak somewhere, but I can't find anything just upon inspection. Any ideas?
have the same problem?
