93 Tempo idling too fast...
I've had this problem for 3 weeks now.My 93 Tempo is idling too fast. I replaced the TPS with another good one and there is no change. I checked for vacuum leaks but found nothing wrong. I cleaned the throttle plate as well. Any one know what could be wrong? A sensor... which one? Thanks Mike

idle air bypass valve
Ford built poor ones these years and they sometimes fail allowing air past they shouldnt, causing a high idle.

I think I might have the same prob too..
Hey there,
I think I might have the same prob as well. I replaced my Air Filter and Fuel Filter. It runs better (Not dying) but, now there is a slightly high idle. I also hear a slight scrill coming from the passenger side. It is kinda near the back of the engine and again passenger side. Slade

Re: 93 Tempo idling too fast...
sladezero, mind me asking what in the world a "scrill" sounds like? yes, we can all go replacing things and hope to fix the idle, or we can do it the easy way and not pay anything. release a small amount of pressure off of the throttle cable by readjusting the nuts where the a/c adjusts throttle when the compressor kicks in. when adjusting these nuts be VERY careful. shift it around too much and it will take you forever to get it back to where you started.

It sounds like this......
Hey there,
It sounds like air but, a higher pitched air sound. After I drive around a little bit it goes away. Go Fig. I guess I will have to check after TG. slade

Re: 93 Tempo idling too fast...
oh, i guess you meant to type shrill? or maybe you really meant scrill, and my vocabulary is much more limited than i though. i don't know why there would be a "scrill" at first, and then it goes away. does sound like a puzzler. a scrill sounds to me like a vacuum leak, but i don't know why it would go away. good luck, and happy thanksgiving.

Re: 93 Tempo idling too fast...
Did anyone bother to check the idle screw? Yes, there is one on those years. If you adjust it down, it might make a difference. If it's adjusted too high, the idle will be too high. It's on the throttle cable/butterfly assembly. Just look for it.

I have a 93 tempo
I had the same problem with mine the problem was that there was entirely too much timing in it for the knock sensor to compensate for.
I suggest that you unplug the modulator from the distributor then loosen the distributor start with a 1\4 inch turn and go from there, once your within about 15 degrees the sensor should be able to control your timing. Your problem sounds identical to mine so if you have no leaks, your TPS sensor is good, your a\c switch is good, and your MAF, and IAC check out fine, its going to be the timming I'm sure of it, I hope this helps you out and good luck to you sir.

Ironic
Hey there,
The ironic part is the car is now my father's. I got everything running and really did not need it anymore since I have my Saturn ION that gets 35 MPG with it's 140HP 2.2Litre engine. I do appreciate all the help. Hopefully this has helped someone else as well. Slade
