1984 F250 engine miss

Engine was missing badly. Took it into shop. The rebuilt carb. replaced sparkplugs and wires, distributor. Still engine is missing bad. They say there is a vacuum leak of some type on the power steering pump? Does that make sense? I was thinking fuel delivery (pump or filter.)

Its a bad valve, get your heads eplaced or rebuilt, if you dont the valve will drop into your cylinder and destroy the piston, i had the same problem and i didnt fix it and that truck no longer exists

Engine misses when going up incline until I let off gas


Missing under load can be caused by a number of different things including:
a bad sparkplug
bad ignition wires
if your car is old enough,
bad distributor cap

Also, it's possible it's missing all the time, and you only notice it under load. If so, then add
bad valve
bad piston or rings
blown head gasket

I have a 98 GMC serria 350 Vortec I had engine rebuilt. I didn't have a misfire before I had it rebuilt but now I do. I replaced ICM ,Coil , Pickup coil ,sparkplugs, sparkplug wires, cap & rotor had it...


There's a lot of things, or combination of things, that could be causing the problem but you could have valves that are adjusted just a little to tight which can cause a misfire as the engine warms up. Other things that come to mind are vacuum leaks, fuel pressure regulator leak, or an injector problem. Don't have a silver bullet for you but that's where I'd start my search. Hope this helps and good luck!

Hi,
Chances are this just a random engine misfire caused by bad spark plugs or bad ignition wires. Basically get a tune up and replace the ignition wires (spark plug wires) and your problem should be solved. Have a good day.

My Ford F250 has an intermittent miss. I have replaced the spark plugs ,wires, cap and rotor. When I replaced the Spark plugs the miss went away for 1 day. The next day the miss came back when I started...


You can find the miss by starting the engine and pulling one plug at a time. when you find the one that doesn't change how the engine runs, there is your problem area. things to do are, first I would switch the wire and see if the miss goes away. If it doesn't then pull the plug and see if it is fouled out. do a compression test on that cylinder. if the compressionis low you can spray some wd40 in the cylinder and retest. if the pressure comes up then the rings are bad, if it doesn't then you have a valve problem.let me know

Engine missing and bad idle,


Hey, i may be able to help you,you should just let me know if you have a auto timing or normal manual timing,
in other words,do your ajust the timing on how fast you are driving or not.

About your wires arcing out of the boot,dialetic grease is a real good thing but as soon as it gets wet it tends to get thin and then leads away your spark.
Clean them off and use it with out the grease and see what happens,

you can also try and spray the plug on that metal hex with a clear coat and also around the plug hole...

Hope this help you...

Regards.
