I've posted this question before, but maybe I can get a few more opinions.

My 5000 2.2 liter runs great, never overheats, gets good mileage, and passes smog after it's all warmed up. However, it's hard to start when it's cold, and takes me holding the pedal down to get it to idle until it warms up.

I've done a bit of diagnosis, and I do have the Bentley manual and quite a bit of mechanical aptitude, but I'm stuck. I removed the cold start injector on a cold day and craked it...and got nothing. I think my problem may be the thermo time switch, but I'm not sure how to test it. Can I stick the wires together and try to force the cold start injector to go, or should I try somewhere else?

Also, the car always diesels badly when I shut her down. It's runs on real fast for a couple few seconds...sometimes backwards. The car's been treated well it's whole life and I just replaced the rotor, dist. cap, plug wires and plugs. Could the two problems be related? Thanks...

 

you could have a problem with leaky injectors ... the injectors are supposed to hold fuel pressure, but if there bad they leak -> no fuel pressure -> lots of cranking required before fuel pressure biulds back up ... and also check for vacum leaks
