1998 Chevrolet Lumina LS 6 Cyl 3.10L

Engine

Engine starts, then stalls no more than a minute later

My Lumina (184,000 miles) made the 10 mile drive home from work with no problems. I parked it, then started it again about 15 minutes later, pulled out and turned into a parking lot where it sputtered and died. I started it again, pulled out of the parking lot and turned onto a (thankfully) very unbusy street where it sputtered and died again. I let it sit overnight parked on the street, found a nearby mechanic with some decent online reviews, started the car and made the 1/2 mile drive to the repair garage with no problems.

The mechanic calls, not surprisingly finding multiple issues with my old car and its engine, but the only thing he said he found consistent with the symptoms was a throttle position sensor that kept failing his diagnostics. Cost to repair: $300, significantly higher than the $175 price I see on AutoMD. Do you agree that this would cause the problems I described, and is the extra cost explained by time needed to track down the problem or am I being ripped off?

Yes, this could be the issue with the car, and the price depends on how much the part cost is. You may ask him what the new TPS costs and find one cheaper yourself to have him install if he is ok with that. He may not give you a warranty on labor if you take this option. He may also be performing other work in addition to the TPS,

I haven't asked the mechanic what his price was for just the part, but searching on Google gives me a range of around $55-75 for a TPS. Thanks for the response!

Also, the mechanic didn't mention any other work done both when he called to give me the estimate and when he called to say the work had been completed.

Just to follow up... from the mechanic's bill the extra cost looks like it did come from the extra time needed to run diagnostics. 1 hour of $90/hr labor (as posted on their wall) to diagnose 1 more hour to install a $90 TPS (higher than a Google search values the part, but not unreasonably so) equals $270, round about what the bill came to. I'll take it. That fixes a probable cause for the stall... time will tell if it fixed the actual cause. :-)
