My 1990 240 has just started exhibiting some reluctance to start when it's hot out, either over 90F or 85F if the car has been parked in the sun. The engine cranks over and over but there's no indication of trying to start. After three or four attempts it thus far has then suddenly stared normally.
Prior to this, possibly related, I noticed than once in a while after starting the car, the idle speed was rather low and most of the idiot lights would stay of. Bumping the gas pedal turns the idiot lights off and restore normal idle.
The car runs normally. It gets 24-25 mpg in mixed driving, which has been the case for the six years I've owned the car. No loss of power, no stumbling or hesitancy.
I haven't checked for fault codes yet. Any suggestions as to the possible remedy are much appreciated.
