Help, i have to go on a trip and here is my problem. I have a little rought idle, when i hold the car at a constant rpm the engine stutters. When i push full throttle its fine. What could the problem be?

Your coupe is digifant - has no potentiameter IIRC.
Maybe check codes?
So It's studdering under idle and part-throttle, but not when you rev it? When's the last time the basic plugs/cap/rotor have been done? Check those, could maybe be an injector problem? I'm just shooting off ideas on that one.

Well I thought it had a TPS, but now that I look it lists a potentiameter. Really, I'm the last guy to ask, I don't know much on the 20V digifant. I figured it was a TPS type system, but I guess not. So yes, I'm totally wrong. Hopefully someone else can help you more on this one, I'm not much help :-(

Not a throttle potentiometer. If the car runs fine, but when you come to a stop it dies, it is probably the idle switch.
On the early 90 coupes the idle switch and potentiometer were two separte items. On the later 90 coupes they we combined. This is unfortunate, because the combined unit is about 200 dollars.
Check out the site I have attached. It gives a procedure for checking out the unit with a Multimeter. Don't have one. Buy one. Cheap and can be used to track a lot of headaches.<ul><li><a href="http://20v.org/throttle.htm">http://20v.org/throttle.htm</a</li></ul>
