What is wrong with a 1994 Ford Tempo if it sputters like it wants to stall when you are at a stoplight and the RPM gauge goes crazy?

When I've had that problem it has always been one of two things. 1) TP (Throttle Position) sensor or 2) Air flow sensor. Both typically being over $150 if taken to a mechanic. Hope this helped.
If you remove the Air Flow Sensor (Takes a special star shaped socket with a hole in it) and remove the top cover of the Air Flow Sensor and clean it off by spraying it with electrical cleaner till it is a shiny silver again. that may take care of the problem also. After I did this on my 92 Tempo, it ran like new! There is a O-ring seal that you have to be careful not to damage. When you tighten the cover back down, just snug it up good - don't over-tighten it. The Air Flow Sensor lets the engine know how much air is coming in so it can increase the amount of fuel that is being sprayed into the throttle body. I am not sure what you mean by the RPM's going crazy? Is it like the engine surges? You could also possibly have a vacuum leak somewhere.
AnswerThere is a vacuum hose on the left side of the engine towards the rear. Make sure both ends are plugged in. It can get disconnected while working on the engine, and it can pull itself out. It will cause your problem.Wiki User
