I've been searching the newsgroups for an answer to my problem and thought I'd be better off posting, so here goes!
I recently purchased a 1989 F150 Supercab 5.8 V8 EFI, Automatic, with dual tanks for summer camping and other occasional use. When it starts the idle lopes from normal on down - never races - and eventually stalls. A few times the truck has stalled while driving, but I was breaking a little harder than normal both times causing the RPM's to go down. Of those two times, 1) Freeway: engine stalled when I pressed the gas, but kicked back in 2) Surface Streets: engine stalled completely, but I turned the key and started right back up while still rolling.
If I give it a little gas, it does just fine. It also seems to perform very well at driving speeds, power seems good - but I don't have the best point of reference as my other cars are a v6 mini-van and a 4 cyl accord. We also acquired a camper recently and the truck did just fine with the extra load bringing the camper home - other than stalling at the occasional stoplight.
The previous owner said that it had this problem before and a new Fuel Selector Valve / Reservoir fixed the problem. I replaced that, but no dice.
- I've just changed the oil and it seemed normal.
- There was oil in the air filter and the breather was shot. There were some small carbon deposits in the air filter housing as well. I Cleaned the K&N filter and replaced the breather and wiped out the housing. The oil in the housing did not seem watery or milky.
- PCV Valve still rattles
- Changed the spark plugs, but still need to check the wires and distributor.
- When I turn the car off there is a "whirring" noise for about 20-30 seconds that eventually slows down and goes away. It seems to be coming from the driver side of the engine compartment.
Anyone else had these problems and fixed them? Anyone with a possible solution?
Thanks so much!!!
