I went to Auto Zone and got codes. Yikes I have 5 different ones. Guy said all but the first could be linked to transmission. So here‘s the codes: PO171system to lean, bank ox; PO743torque converter, circuit electrical; PO1401Manf. control auxiliary, emissions controls; PO1507Manf. control veh. speed, Idle speed control, auxiliary inputs; PO1744Manf. Control, transmission. I had the transmission replaced with used one last year. It seems OK, but after I drive it a while the OD light starts flashing. But the real rough idle when car is stopped is really bothering me. It is worse when it is in drive, but still bad when in nuetral or park, so it may be related to transmission. It reminds me of the way a stock car idles, but my car is far from being race car. PLEASE help! Also, if you know where I can get suggested parts at a good price please let me know.
1. Stop going to autozone for diagnostics. 2. Take your car to a reputable shop, for a nominal fee, they will find out what's wrong, and give you an estimate for repairs. Good luck. I would find a different shop. If he is using the same equipment as the autozone kid, he isn't keeping up with technology. As far as parts, I guess the best place would be the dealer. But again, without knowing exactly what is wrong, why start throwing parts at it?
I have to agree with the certified mechanic who also answered you - partially. The AutoZone down the street from my apartment has employees who have worked as mechanics and are/were certified. But I estimate that 95 out of 100 auto parts stores (regardless of the chain or franchise) don't have knowledgeable employees. So, yes, take your car to a reputable shop (or the dealer - if you don't mind paying a hefty price) and have them look it over. Get it fixed, then, if you still want to save a buck on diagnosis, ask around to find out if any of the employees of any of the parts stores around you have ASE or similar certification. Don't take the word of anyone who hasn't spent half their life studying cars and actually working on them. Listen to the certified mechanic. There are too many variables to give an online answer to your problem. Take the car to a shop and fork over between $40 and $100 for them to do a computer diagnosis on it (estimated price range in the lower 48 here, in the USA). That estimate is based upon most places either charging a minimum of ? hour or 1 hour labor just to hook up the computer and read the codes and try to come up with a diagnosis. Further troubleshooting will probably be necessary - most likely at an hourly rate. Then there will be the actual repairs.
