have a 98 rodeo, with a V6 & Auto trans. have an intermittent problem - as I am driving engine will occasionally drop to idle speed and then pick back up to driving speed. Engine keeps running smoothly, just at idle speed.
CEL does not come on / no codes
Replaced Throttle Position Sensor - and thought I had found the problem, but since it is so random, it just didn't happen again for 1 1/2 weeks.
Anyone else have this issue?
Suggestions?
