Hi,
So, I've just replaced my external fuel pump, fuel pump relay, idle air control, air mass sensor, thermostat and done a full tune up and my car is still having problems. Half the time the idle drops like it's going to stall out- but doesn't- and the other half of the time it runs smooth. And then sometimes, it just won't start- cranks but doesn't catch. Despite the battery being only 2 years old I've found that I can usually get it started with a jump. This seems weird since when it won't start the lights/stereo/power windows all still work. Mechanic after mechanic seems to be stumped by what's wrong with it and frankly I've run out of money. This has been a great car- only has 175,000 miles on it and has taken me back and forth across the country multiple times. I've been extremely anal about regular maintenance and love my brick, but I'm beginning to think maybe it's time to ditch the beast.
Does anyone out there have any ideas of what could be wrong with it? Please, I'm at a loss!
Or, can anyone give me advice on a trade in I'm considering for a 1989 240 DL wagon...

Cheers,
Celise
