thanks Rob, I'm trying to pin down any and all possible causes for a
lousy idle. After 'fiddling' I seem to be only making things worse. Now
when starting the car, rather the idle at 80 or 900 like it used to, it
simply stalls instantly,,,, can't understand it.
again, thanks for that Tiger. I'm beginning to grasp at straws re the
lousy idle of my '89 300E. Most recently, after starting easily, it simply
dies.... doesn't even try and hesitate and attempt to idle. After 'slowly'
taking foot of gas pedal I can eventually get it to idle very roughly around
500 rpm or less... and it's die at the slightest provocation such as putting
it into drive. Just a few days ago, when cold, it used to idle correctly
around 800 or 900. Stopped doing that compeltely. Checked all the hoses,
sprayed propane around with no affect (except if I spray it into the air
intake). Replaced the O2 sensor and it works as it should judging by the
scope and direct voltage readout.... cleaned the air bypass valve which
works when applying voltage directly.... Cleaned the distributor cap again
I did notice though that all the points were quite pitted and some oxide was
showing on them as well. I guess the next step is to simply replace it to
see what that will do.... I just don't get it.
