So today is the first time since I bought my 91 that the check engine light came on on the freeway. Im thinking it may be the AEM intake getting a little mist or water since the headlights are up. Also, last night without rain, if I hit the throttle real quick rpm would go up, then dip to about 200 then settle back around 700. Any ideas before I throw money at autobacs to fix?
Thanks!

Possibly could be coil packs arcing or spark plug wires

you should check to see what the ECU code is before you buy anything.
