I would recommend getting a tune up first and see if that changes how it runs.Also change your fuel filter and air filter.If it doesn't change then it could be a vacuum hose that's off or broke.Also Buy some Techron fuel injector cleaner and dump it in your tank this will help clean your injectors.Since there is no mention of a check engine light being on then this should help.

Runs smooth then runs rough & rough back to smooth running.


If your check engine light comes on get it checked. To me it sounds like an engine misfire probably cause by a coil pack or spark plug wire going bad. The misfire should cause the check engine light to come on maybe even flash if the misfire is bad enough

94 camaro v6 engine and the idol runs at 2000 rpms, runs even higher if heater switch is turned on. shop cant figure out issue any ideas?


Not much of a repair shop

Use the codes & reference material to diagnose
the problem

No reason a repair shop can't do that

Leave it there until they drive it & the light comes on

They have a scan tool & have to use it on a road trip
& record the data

I have a 2000 cavalier auto, 2.2 eng. will it run or even start if one of the injectors are not working. I think one of the leads are bend and its going to be a large tow bill to get it to a shop. I would...


It will start and run even if you have two injectors that aren't working, it will run on 2 cylinders! BUT it will be hard to start and when it starts it will run rough and have limited power so I hope that your shop isn't too far away.

My 1994 Altima has always had rough idle but runs smooth. I now have 176,000 miles on it and drive it daily. Best car I ever owned. I wouldn't let the rough idle bother me.

Get the codes that were saved when the "engine light" came on and post them here. (You can get them retrieved for free from Auto Zone).

I'm going to take real *wild* guess that somehow that rough spot you hit actually impacted the oxygen sensor and disconnected it or damaged it.
