amc motors

i cant get my amc car the renault alliance to run very good. Sometimes it runs and sometimes it dont.
i even had the local professional mechanic look at it. but they didnt know either. any ideas

Get a good manual and / or take it to a better mechanic. There is no reason why an AMC can't be made to run good.

What are the symptoms? Perhaps we can help. I have worked on these in years past. It CAN be made to run well.

We need more info than that. It sounds like it could be a sparkplug issue or it could also be a loose fitting nut or oil it could be ANYTHING.
