Question about 1998 Ford F150 Regular Cab

1 Answer

Idling on my truck fluctuates...

I recently had my truck die out and found that I had to clean my terminals. Only when I started my truck I found I lost some power on the take off and when I stop at a light my truck shakes noticably. I just changed the spark plugs about two months ago after dealing with the same problem and it seemed to correct it. Now with it doing this again I am running out of ideas as to what it may be. Any solution would be most helpful.

    Have a 1981 Ford F150 Pickup truck, and when I start it up and rev it up for a few minutes and then let my foot off the gas, it stalls or runs real rough, then dies. Sometimes it stalls at the worst times while driving around town.

    I changed the spark plugs, which were overdo to be changed, new breather filter, oil change and filter, new battery.

I had a similar problem to bojangles830. Check your ground cable from the battery. It runs down to the starter and from there to the frame. A corroded ground cable was the cause of mine. I don't suggest buying the cable from Ford. They're way to expensive. You can get cable and terminals from any auto parts store. If you have access to a vice and possibly a hacksaw you can do it yourself cheap. Also, use an anti-corrosion treatment on your battery. For some reason these 4.6 liter Fords are prone to this particular ailment. Good luck.

My car will start and idle fine sometime and sometime it dies and dies when put in gear

Engine stalls cold or RPM fluctuates at idle up and down or dies near idle.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control. If the above cleaning doesn't cure your issues you need to have the computer controlled automatic idle speed control system diagnosed and repaired by a dealer or electronic engine control repair shop.

Did you clean out intake and spray throttle body with cleaner? I has the same problem, removed intake manifold and cleaned out goop that was preventing the recirculation of air in the engine. Try to google the problem. I found instructions and a pictorial.

Hi there, Please be informed that sometimes RPM is unstable. Sometimes it's almost 1000 sometimes about 800 or less (in the same conditions: without A/C, lights,...) It is slowly fluctuating and...

I'd start by replacing fuel filter. I'm assuming it's been recently tuned.... If not, replace plugs, wires, all fluid & filters and run a good fuel system cleaner through it.

Just changed battery. Rpms are lower than normal at idle. It's dying when stopped for any length of time.

All you can do is drive it tell it relearns, This is common when the car losses power. You could try clearing codes. This puts the Idle Air Control valve a a preset postition. Disconnecting the battery sets it at 0.
