Our normally reliable 240 with 125K miles is dead out in the driveway.
She turns over and coughs occasionally but that's it. The car normally
runs very well except for the clues below.
Possible clues: For a while there's been occasional throttle hesitation
coming off a stop when the engine is cold. Also occasionally, it's hard
to start, requiring application of gas pedal or it stalls or nearly
stalls. Other times, perfect.
Another possible clue: it's been cold (25-30 F) and wet here lately and
the car sat for a couple days undriven before this problem.
I mentioned the hesitation and hard starting to my mechanic a few months
ago and he said the air mass sensor was probably going south. He said
it'd probably get hard to start once the sensor was really failing for
real.
Any ideas? I'd love to get it running without towing it the 30 miles into
town!!
