When I started my car this morning the check engine light came on AGAIN.
I bought it brand new in 2003 and it has 42,500 miles on it. This is the third time it has come on. The first time it went off by itself before I had a chance to bring it to the shop. The second time I brought it to the dealer and it was the oxygen sensor. NOW it is on AGAIN. I have my doubts it could be the oxygen sensor, I mean, it was just replaced about a year ago. But what do I know. I am just a girl, so a walking target if I do bring it in. I think it is now out of warranty time, which is just my luck. Could it be that we are having a " cold snap". Not that cold considering I live in Florida, but it is colder than it has been by about 20 degrees. What can I do myself before bringing it to a shop and being completely over charged? Should I just cut my losses and get rid of the stupid thing?
Take it to a tune up shop and get them to hook it to their diagnostic computer, which should be cheap if not free, depending on the shop. Get a print out of the diagnosis, then go from there. It may well be you can fix it yourself. I DON'T agree with the " I'm a girl" thing, women can make fine mechanics, too. Invest in a repair manual for your vehicle that preferably lists the codes and their meanings, and do some reading. It may seem hard at first, but it really isn't if you have a good guide.
