I posted a few months ago and got little response. Check engine has been on in my 2001 Daewoo Nubira for probably a year, maybe more (101k miles), but mechanics have never mentioned it, even when I've gotten it inspected.
It's past time for an oil change though, so I took it to the Meineke across the street. He said he'd fit me in shortly, and just as I was walking back out to the car, I asked if they would also run the codes for me, explain what they mean, and just guestimate how much it'd take for them to fix the problem(s). Seems like a fair request to me. It'll take them 5 minutes. AutoZone took even less than that, and for free. At Meineke, his response was, "Oh, okay, but we charge for that." I said, "How much?" He said 49.99. And I said, "Really? You'll take a look at any other problem and tell me what's wrong with it... before you charge me anything at all. You did it for me just a couple months ago. But you can't run the codes just to give me an idea what might be wrong?" He insisted there would be a charge even for a minimum of work if they ran the diagnostic, and I said forget it and walked out. The irony, of course, is if he had run the codes... I probably would have gone back for the repairs... which probably would have cost well over $50. But money is tight, and it seemed like a money grab. Anyway... is this normal? If so, why?
That all said... hopefully someone here can give me an idea. Car runs fine for the first few minutes... after probably 15 minutes, it sometimes (not always) seems sluggish and may sputter a little when I hit the accelerator... and also when upshifting, especially around 4th (it's automatic). Usually if I give it more gas it powers back to life, although it may lag and I may have to back off the gas completely for a split second before giving it gas again. It's especially noticable in stop and go traffic. It seemed like a timing or some sort of sensor issue to me but I really have no idea.
Codes from AutoZone are:
P0342 - Cam sensor condition - The camshaft position sensor signal is monitored for errors
P0463 - Fuel level sending unit - poor electrical connection at fuel level sending unit
P0742 - TCC stuck on - TCC commanded off by the ECM, TCC slip detected after off command
P1627 - Analog to digital performance - The ECM has detected a fault in the A/D converter within the ECM
There are some probable cause listed... but what do you think? More importantly, how severe are the problems, individually and in their entirety... and how much will it set me back to get it fixed?
Thanks for your help!
