Thanks everyone.

New fuel filter and tune up 2 months ago. Is the temp sensor easy to replace yourself? This is the coolant temp sensor you are speaking of?

Thanks for all the replies. I had first put the car into a auto shop. They said it was an electrical problem so I put it into an electric shop and they did computer diagnostics on it and claimed there were no fault codes and that I needed a new fuel pump. They guy said the fuel pump pressure was too low. Would this necessarily mean that the fuel pump is bad or could it be a bad sensor of some kind sending the wrong info to the fuel pump or computer? I forgot to mention in my earlier post...If I unhook the battery for an hour or two to reset the computer, check engine light goes off and the car will start up fine and sometimes run for a day or two with no problems until the check engine light comes back on....then its back to where it idles strange and wont start, etc.

I know very little about car repair so please forgive this post if it sounds stupid. I own a 1993 SUBARU LEGACY Wagon 4 Cylinders 02212 6 2.2L MFI and recently took put it in the shop for a starting problem. The car will start normally in the morning but after it warms up to normal operating temperature the Check Engine light comes on and if you are sitting at a red light the idle will go up and down, sometimes getting really low where the car nealy dies, then reving up to a higher than normal idle. Then if you stop the car and try to restart it again before it cools down, it either wont start at all or is very rough starting. The shop says its a bad fuel pump and quoted me a price of $350 parts and $200 labor. Is this a fair price? Can anyone tell me where the fuel pump is located on my car? Thanks for any help.
