2002 Subaru Forester misses/runs poorly with slow acceleration when hot with a/c on especially after running 50-60mph on interstate. Problem is intermittant. Runs fine with excellent acceleration...


I have the same problem. But my check engine light comes on when this occurs. The car runs fine otherwise. The problem manifests when it's hot out and I've been driving for a while with the A/C on. When I stop somewhere (like the supermarket), shop, and get back in my car. It starts fine but when I put it in gear to go, it's extremely sluggish for a few seconds and the check engine light comes on. Then is runs fine but the check engine light remains on. The next day when I start it, the check engine light is not on. Also, I recently had the head gasket replaced. I took it back into the shop the first time the check engine light came on. The mechanic checked it and said everything checks fine. He re-set the light saying to keep an eye on it and bring it back in if the check engine light comes back on. It ran fine for 1.5 weeks and now this problem has started to occur.

Did you find anything out dwbradway? I wish I had a solution for you but I just have the same kind of problem. Any help would be appreciated!

Check engine light stays on all the time, but car runs fine?


Well, the engine management system has something wrong. Pull the codes and explore the code(s) given.
Car running fine with the check engine indication is not unusual. Something is wrong, get after it.

Check engin light stays on. Starts fine runs


Most common cause of engine lights is either an air fault such as air flow meter or air mass sensor. there are others but if the car is driving fine then most likely an air fault.

Check the air sensor sometimes they just need a clean up rather than replacement.
Let me know if you need more info.

The check engine light came on it seems to run fine the only other thing i noticed is the temp gauge runs up to 210 then comes back down,it only does that right after you start it then its fine


Check engine light can be any number of reasons, dirty air filter, need oil change, or more serious engine trouble. The temp gage issue is normal, this is the computer resetting itself. My car the fuel gage and temp gage do this...don't be alarmed. Take it to Advance Auto Parts and they can run a free engine diagnostics test on it to see which error code is tripping your check engine light.

Mechanic says camshaft sensor needs replace; however the car runs fine. Check engine light comes on sporatically.


Agreed with thundergod - I had a failed cam sensor on my Audi A4 that made no discernable difference in the car's operation, but changing it and resetting the light fixed the problem.

2001 rodeo, red check engine light on


The check engine light indicates a problem, many times the car will run fine, or seem to, but u should get the codes read to determine what's wrong, and correct the problem, as it can lead to other troubles. Not sure about parts stores in Australia, but in the US they offer free car checks of trouble codes when the engine light is on. They plug a hand held scan tool into a port under the dash, and 'read' any codes stored in the cars computer. Write down the numbers for your records, and ask them what the codes mean, and how to fix the problem. If u have any questions, post them here w/ the codes for help.
