1993 300E IDLE PROBLEM
Hello, I have a 1993 300E Mercedes, 6 cylinder, fuel injected w/ 155,000 miles. The problem is once in awhile when the car is first started (cold), it surges from 350 to1300 rpm (about). After the car has been driven and warms up, it has no idle problem, unless the car idles for 10 minutes or so, if you give it gas to move, it then begins to surge. If the car is turned off and allowed to sit for 10 to 20 minutes and then re-started it idles fine.
I have changed the mass air flow sensor, with no change…. Fellows I need some help!! Thanks 300ebess
