RPM drop/fluctuation
First Post.
I drive a stock '90 RS V8 5L. When I'm "idling" in gear. (foot on the brake at a stoplight or foot off the brake but no gas engaged) I notice the engine drops 5ishRPM and then back to idle rhythmically. In some cases this causes my engine to shut off while in motion so it is dangerous.![Frown](https://www.thirdgen.org/forums/images/smilies/frown.gif)
Sorry if this is poorly-worded. What could this be? I have very little car experience.

Welcome aboard thirdgen.org.
I moved this to the TBI forum. Figured you're more likely to get useable responses here.
