I was in my 1990 Oldsmobile Ninety Eight in a drive thru this evening when I noticed the temperature to start to creep up and the car began to rev high for a moment then go to low idle and stall. I backed out of the drive thru and parked it and it did this once again, but then after I started it, it idled fairly well and drove perfectly. I want your guys’ input but I feel like it’s the fuel filter for the following reason:
Coincidentally earlier in the day I ran the car somewhat low on gas (~3-4 gallons in tank) before getting gas. I feel like I could have ran it low and some of the 25 years worth of sediment could have caused the fuel filter to clog. However, after this incident the car ran good under heavy acceleration which makes me think this might not be the problem.
I wanted to share this with you guys and get your input…please let me know what you guys think!
Thanks in advance

I would say a fuel filter is a good place to start. Not that expensive. Dump
the old one out backwards in a jar to see what comes outhttp://www.ericthecarguy.com/faq/solving-automotive-performance-issues
Update: Today I took the vehicle to a local mechanic. He said that he scanned the car and several trouble codes came up for a bad MAF sensor. Sure enough, the MAF sensor housing had a strange crack in it, he replaced it and the car no longer died at warm idle. However, as I was driving the car this evening and went to accelerate hard, it stumbled and nearly died but didn’t. I don’t know what to think at this point, but I still haven’t touched the fuel filter and there’s the possibility that the fuel pump is down on pressure. It could also be plugs/wires or ignition coil. Another possibility that I thought of was the transmission, as it mainly stumbled only when the tranny is about to kick down.
As a side note, the mechanic also claimed that he cleaned the throttle body so idk if that could maybe cause an issue if it wasn’t cleaned well enough.
Thanks for your guys’ input.
Well, if he replaced the MAF sensor housing and got dirt on the MAF sensor, that can cause problems. MAF sensors are sensitive to foreign substances on them like oil from your finger, etc. So it’s possible he gunked it up. I would still have a look at the fuel filter. If you haven’t replaced it for a while it would be a good idea to do it anyway, as the problem could be caused by low fuel pressure as well. If that doesn’t work, you can worry about the MAF sensor later.
