hey guys very nice discussion i took my car for the lumpy idle too and the dealer said that the supressor switch was bad picked up the car on friday no problem fri and sunday but just before today i felt it again it doesnt do it all the time after the car runs for approx. 30 miles it does it will contact the dealer tomorrow they cant fugure out the problem either this is the third time it went in for the same problem any idea what it could be other than a bad supressor switch just changed the spark plugs last week and teh dealer said the wires are still in a good shape no need to replace it
by the way i have a 93 400 e
thank
