I have an 88 300e it will start fine when cold drives good but sometimes will stall at stop and then does not want to re start. It backfires and kicks back then sometimes it will catch and start and run fine . Other times runs and drivs good but doesnt want to re start after sitting a few min other times starts right up I have replaced fuel filter plugs cleaned intake and injectors. Can anyone Help Please! Thanks

 

timing.

check the timing: ignition, camshaft.

check secondary ignition area.
