Daniel Posted April 25, 2023 Share Posted April 25, 2023 Hello there, I have an issue with my MB6 B18C4. The engine sometimes hesitates sometimes not and the car has very bad idling. It fluctuates a lot. New distributor, new TPS, new MAP, new IACV, new throttle body, new spark plugs and spark plug wires and the car has enough coolant in it. Any ideas?

finjj Posted November 7, 2023 Share Posted November 7, 2023 Haha i have the same problem... i have done almost all the same things. Im suspecting the coolant sensor under the distributor. But update if you find the issue! Quote Link to comment Share on other sites More sharing options...
Dave Posted April 3 Share Posted April 3 Have you tried cleaning out the vtec solenoid? Sometimes helps. Does it do it both when the engines cold or hot? Another thing to check is fuel filter, most have probably never been changed so could be well past its best. Quote Link to comment Share on other sites More sharing options...
