Hey, I have a problem when I try to start up my car. It's a 95 Mercury Mystique, Zetec engine, auto. When I start up my car, it idles around 2k RPM, when it normally is around 1k RPM. This started about a week ago, when it only seemed to happen about 50% of the time. Now it's much more frequent.
Driving around doesn't seem to have much of an issue, however sometimes the car jerks, or suddenly drops in RPM and then picks up again. It hasn't stalled on me yet, but it has come close once or twice. I was searching the forum on here, and it seems like it could deal with the computer "making bad decisions" And that a reset was needed. I was supposed to clean the throttle body and the IAC, however could not find them in the engine bay. I did remove the terminals from the battery however, so that the computer could at least reset. When I started the car, same problem occurred.
My check engine light goes on after a bad start up, and seems to go away after about 5-10 minutes of driving. However when my car jerks, or has a sudden drop in RPM, the check engine light comes back on. The oil, trans, and coolant fluids are all ok, and I just got my oil changed roughly 3 weeks ago. I haven't had any major work on the car, but I did get the front end re-aligned with new tires. The car only has around 86k miles, and is a '95.
Another interesting piece of information, when I drive, let's say I bring it up to 4k RPM in first gear, and then take my foot off the accelerator, it seems to drop extremely fast down to about 1k RPM. Perhaps I'm just looking for things that might be wrong with my car, so this might not even be a problem (or could be normal for the car).
Anyways, anyone have ideas? Someone at work suggested injector cleaning fluid, which I just put in my car tonight... Fingers crossed on that one. I thought that it might be the problem with the computer needing to be reset, and the throttle body and IAC being dirty, however shouldn't it start up just fine after resetting the computer? At least, that is my thoughts on it, and I could be completely wrong. I'm not a car expert by any means, and I'm looking for any advice on how to fix this issue. It might not be a major issue now, but I don't want anything major to come of it.
Thanks in advance
