Engine 'convulsing' below 1k RPM

vendaz · #1 02-06-2004, 10:47 PM

Hey people,

I have a '90 MX6 that just this week started acting up -- whenever the engine is running and the RPM gauge is below 1,000 RPM, the engine starts revving up and down really violently. I have to hold the brake and gas pedal above 1,000 to keep it from doing it, and even then it shudders.

Could this be a gas line problem? It drives fine when above 1,000 RPM.

you seem to have an idle control motor/mechanism either broken or hanging up....that is where you need to start looking
