I have a 89 5 speed with no real serious mods, and runs absolutly great. The only problem I have is on damp, rainy days it seems to not respond as quick as usual and have a high idol (1100 to 1200rpm) only for about 3 mins until it warms up, then it's back to running great. Could this be a sign of my DIS going out? Thanks.

When is the last time you put new plug wires on ?

About 3 weeks ago, Good ol' Tim gave me a hand doing that FUN job! Yea and I forgot to mention this has always happened since I bought the car approx. 1 year ago.

Sounds to me like your IAC only because once its all warmed up she idles fine. Some go bad in funny ways.
