My wife's 1990 Buick LaSabre with 148,000 miles on it is being quite evil right now. : Evil:
Don't know if this has anything to do with its issues, but when she let the car get down to 1/4 tank of gas, it'd start sputtering, she'd fill it up, and things was fine again. Last Friday this happened, only things weren't fine anymore. The Service Engine Soon light came on and off, and on and off, and so-forth. As the car is driven more, it will sputter and stall more. (Also, she thought she smelt fuel once and awhile during the past month, but nothing leaked on the ground. Also, the vent switch started working and not working. With warmer air coming out sometimes. And it'd work again if car wash shut off and turned back on).
Two readings at two different auto parts stores gave a reading of 34 - mask air flow sensor. I installed a new one, unhooked the battery for awhile for computer to reset, hooked it back up, turned on car and. Yep. Light was back on and it was still running rough. (I took the part back and put old one back on).
I did a tune-up, new oxygen sensor, idle air control valve, the harmonic balance sensor, additive in gas. The LeSabre is not only evil, I could swear it's laughing at me in the driveway. : Twisted:
So, any ideas on what else to check?
Thanks in advance for all input
