Question about 1989 Ford F 150

1 Answer

1989 Ford F150 idles rough after start and stalls out some

Just replaced the alternator and battery because the voltage meter would be low and fluctuate after every start. The starter has trouble turning engine over sometimes but even when it does the voltage meter still fluctuates a bit and the engine keeps bogging down. Don't know if it has something to do with the starter and sillinoid or if it is fuel related?

Thanks

You need to put a scanner on the truck and see if any codes are set and if so of course repair them and then clear the codes in the computer with the scanner. I would check the idle air control and the throttle position sensor. I would also check the alternator by starting the truck and then taking off the positive battery cable and the truck should continue to run. If not the alternator that was put on is bad.

Was the light on before you changed the alternator? Check a couple of things: Check the connections if one is loose you may be running mainly off the battery but still show it's charging. Have you checked the battery under a load? Try checking the battery voltage with the car off and turning on the headlights. What does it read? 12.2 sounds like you may have a dead cell or if you have a bad connection you may be draining it. Sometimes a battery may show correct voltage but when load is applied it drops like a rock. if this happens replace the battery. Did the idle change when you changed the alternator or has it always been low?

My ford escape stalled on me while driving i had just install a new alternator 1 month ago because it did the same thing


Check your coils on the spark plug, also check your EGR valve and Idle air control valve. Mine did the same thing and I had to replace the IAC, and EGR valve and replace to coils on the spark plugs

Battery lights is on & don't idle correctly


These trucks have what is called a smart charge system. It normal for the alternator light to elluminate when the truck requires no charging or the idle is low. The most likely reason you have low idle is throtttle body coking which requires cleaning or a bad idle air control valve. Also clogged injectors will cause a low rough idle but if that was the case misfires would show up and can be seen while they happen using a diagnostic data scanner.
And the first thing we always look at is the air cleaner. If you have a K/N filter the oil can contaminate the MAF senor. If the sensor cannot see and feel the air then it won't be able to add fuel causing a low idle, The MAF can be sprayed with brake cleaner to clean it. Usually you will get a p0171 and or a p0174 if the maf was causing a lean condition.
