Question about 1987 Ford F 150

1 Answer

I have a 1987 Ford f-150 pickup with a 302 V-8. I will start up when cold (it is a little cold natured) After starting it and you drive it down the road for around 45 minutes and when you start to slow down, it will start trying to die and hesitates and jerks. If you stop without putting pressure on the accelerartor it will die and will not restart. It will restart after a period of time - like 45minutes to 1 hour and run again for a little while and die again.

SOURCE: Burning out the pickup coil in 1986 F-150 w/302

Hello genobeano: My name is Roger and I will give some information that should help. When you replace the pick up coil also replace the ignition module. The ignition module will short out the pick up coil. If the module is attached to the side of the distributor be sure to use die electric grease when installing the module on the distributor. Should you not use the grease you will burn up the ignition system. By the same token should the pick up coil short out the module will burn out. The fact it runs for a short time says that you have a heat problem. Normally is in the ignition system. There was a tech bulletin to replace the pick up and module as a unit to correct the problem.
Please rate the answer as this lets us know you received correct information. Should you need further help please just ask. Thank You for using Fix Ya. Roger

SOURCE: 98 ford e 150 van idles in park fine. But when

Did you try changing plugs and WIRES!! wires are the most common cause of this problem, under load if you have a bad cracked wire it will "leak" the spark causing a weaker spark there for making your spark at the plug weak not burning the entire charge in the cylinder. If this still doesn't solve your problem being the cheap way (im sure it may fix it) try by changing your coil packs let me know what happens. If all else fails you may have a sloppy injector

My 1987 f150 4x4 302 over heats .ive already replaced radiator [w/new] and removed thermostat. does fine on freeway but cant handle in town stop & go traffic w/out overheating so bad the moter shuts...


Sounds like the clutch is gone on the fan you can check it by trying to spin it with the motor off of coarse if it has a little bit of drag maybe going around 1 or 2 times its ok but if it spins real easy and freely it is bad.

I have a 1987 ford f-150 with a 302. I would like to put the 302 into a 1989 ford f-150 that is four wheel drive that currently has a 4.9 in it. would there be any problems with doing this.


302 is a 5.0L v8 engine and 4.9 is a 300ci, 6 cylinder. so you may have problem with transmission, exhaust manifold, motor mounts, vacuum lines/hose, radiator, power steering pump, a/c system, and mostly wirings. not to mention there is a computer in those trucks!

My 1984 Ford F-150 V8 302 choke is not working?


Your choke should have a spring at the bottom under a little cover with a rod coming up and connecting to the butterfly for the choke. Usually this get a little corroded and sticks, you need to clean the pieces so that they rotate freely and the rod will move up and down. It is adjusted on some models by bending the rod to make it longer or shorter. When you push down the gas pedal for the first time in the morning it should set the choke, test this by opening the throttle while its cold out, once the throttle is opened the choke should close, once the engine is running there is a vacuum operated linkage that should pull it back some, until the engine is warm. Again if this worked before, its probably dirty so a good cleaning is in order. Hope this helps, let me know
