I just found this site, and you guys seem to be giving really sound advice.
Here is one that has stumped my mechanic.. (he refuses to charge me if he
can't solve the problem, but he has run out of ideas and apparently, spare
1990 300E with 255k miles. Car runs perfect except... After the car comes
up to temperature, it will sputter, and sometimes stall when accelarating
(hard or soft) from a stop. Runs fine otherwise, with no problems at speed.
This next part is weird. It will ALWAYS sputter/stall when headed downhill,
or turning right. It will rarely (if ever) sputter if headed up hill or
turning left. Seems electrical to me, but mechanic was focused on fuel.
Seperate, but perhaps related: I live in Seattle, and we rarely get any
really hot weather, but a few weeks ago, it went over 100. I stopped to get
gas, and the car would not start (at all) after that. I pushed it out of the
gas lane and into the shade, and waited 1.5 hours. Car started fine and ran
fine all the way home. Problem never repeated itself, but the weather hasn't
been over 80 since that day. I don't think the two are related, but I could
be wrong. Based on some other postings, this 2nd problem may be an
overheated ignition coil.
Both of these problems happened about 3 weeks after the car overheated (badly!
) due to a shot radiator. Guess I need to replace those every 250k miles
whether they need it or not..!
Any thoughts about the downhill/righthand turn sputters?
