This car has been a lemon! It has 155,000 and Just got done changing the water pump and timing belt, and now it won't idle hardly at all. When you are driving it is fine but when you stop it shakes and rattles terribly and feels like it is going to die. The mechanics said it was a tune up problem but it never had a problem before we took it in so we replaced plugs and wires anyways but didn't seem to help. If you rev it up it seems to be fine. Anybody have a clue? I have sank so much money into this thing just trying to figure it out without taking it in. Thanks

 

If the car is running that poorly, I would assume the check engine light is ON. If so, get it scanned and see what it says.
These are my first thoughts about what could be wrong,
You may have a bad ignition coil.
The timing of the engine may be off - caused by improper timing belt installation.
Or something that was disconnected during the timing belt service may have not been re-installed correctly.

You say you replaced the plugs and wires - but the coil-on-plug ignition in these cars doesn't have serviceable wires, so I'm not sure what you mean by that.

 

It ran fine before the timing belt and after the new timing belt it runs like crap?

 

sounds like the mechanical timing might be off a tooth, take it to another mechanic and ask them to check it
