300E runs rough on hot days
Hello Board,
As you all know, my 300E has ate up a lot of $$$ and it is still missing at idle. I have been feverishly attempting to pinpoint the culprit that is causing my 300e to run so rough. I have to suffer while driving in the daytime because if I turn my A/C on, my car will hestiate from the stoplight really badly, to the point of almost stalling. Well what I have come to realize is that it runs rough only in the hot daytime. When I drive at night the car idles a lot better, it does not miss at idle as much and the hesitation is not as bad. Well I have recently replaced my #5 and #6 fuel injector( the worst ones). I plan on doing the whole set next week.
I was wondering if the coolant temperature sensor could have an effect on this weird problem??
Any other suspected culprits??
Parts replaced:
Almost everything
