Okay, i've figured out the shifting problem. I've had this car run on diagnostic machine, everything looked good, according to Midas. They said the ECM has a history of going bad. So I replaced that, still having the erratic idle and stalling. No vacuum leaks anywhere. I'm at my wits end with this car, does anyone have any other ideas...I'm begging...thanks Rick

Say what? a timing in the e?? It has a timing chain, it has computer controlled timing advance, not adjustable. Um...
Such hesitation could be from old, worn spark plugs, old, worn plug wires, a dirty air filter, a dirty fuel filter. (Is your check engine light on when running? If so, look for the trouble codes.) Could be a sensor too, I think maybe the mass air flow sensor should be checked. Another sensor for this could be the throttle position sensor. If everything checks out so far, you should have the fuel pressure tested and checked. Just possibly the fuel pump needs changing. Testing the pressure will tell you.
All I can think of so far, enough to keep you busy checking?
You need to figure out what you are missing. What is the fuel pressure at the rail when you are cranking the engine? It needs to be above 40PSI. If you have sufficient fuel pressure you need to check for spark at the plugs while cranking. If you verify you have sufficient fuel and spark then you need to look to timing and compression. These are the four things an engine need to run. Fuel, spark, compression, and timing.
It sounds more like it's a suspension problem. Pull your from wheels off and examine the CV joints, boots, and take a look at your shocks to make sure they are in good condition. Your diagnostic tool, as far as I can tell, is picking up a problem somewhere else in your vehicle and has nothing to do with your front end suspension.
It definetly sounds like a vacuum leak problem. The vacuum hoses are routed to perform various functions for the engine and transmission. They can be very difficult to track down. They are small diameter black hoses and start at the intake manifold (the source) and go to their respective locations.
They could be cracked, oil soaked, loose fitting, or disconnected to name a few problems to look for. Take it to a mechanic if you do not feel comfortable replacing the hoses.
