Try reseting the computer. Disconnect battery for 10 min. If that doesn't work check for a bad plug, even though you changed them 1 could be bad or cracked?

Every time it starts raining truck starts missing and cutting out it's a 97 f 150 ford 4.6 motor.


Possibly a plug wire or cracked distributor cap. I'd take a spray bottle and while it's running (be careful not to get your body parts in danger of the fan) spray some water on the cap area. If everything seems fine, you could spray down each plug wire at a time. See if you find the culprit that way. For a vehicle so old, if you haven't done a tune up lately. It's probably a good time. Replace the distributor cap and rotor. Plugs and wires.

I have a miss in a 5.7 chevy replaced plugs wires timing chain mass air flagging 1,2 and 3 all have 180 compression also replaced distributor new cap and button


What year? Does it have a distributor? If so, possible distributor cap/rotor issue. If coil over plug, you need to run a compression test to see if a cylinder is weak/valve issue

Tune up 1988 Lincoln Towncar


you need: spark plugs, spark plug wires, depending on if newer system that is all. if it is older you will also need rotor cap and rotor button. label the plug wires and change one plug and corosponding wire at a time after changing the (cap and button).make shure the plug wires go on the new cap in the same order that they came off.

My 1994 ford e350 is used for my motor home. It has a slight miss when driving. i replaced the air and fuel filter, also had the cabon cleaned out of the carbs. I have know purchased plugs and wires and...


When it comes time to change the plugs and wires and distributor cap do the cap and rotor first. Remove the old cap with the wires still attached. Put the new cap and rotor on the distributor and transfer the old wires one at a time. Make sure both caps are lined up in regards to mounting position on the distributor. The cap will only mount one way. When you have this done then you can do the plugs and new wires, again one at a time. This way, when you are done the van should start right up and purr like a kitten. Hope this helps.

I would definitely try the distributer cap and rotor button. It's about a 15 minute job and might solve your problem. As the car warms up the electrical components of course heat up too. As the heat goes up, resistance also increases in electrical connections, wires, etc. You could be getting enough current to pass between the rotor and the poles at low temps but, as they heat up, sufficient current for a good spark is not being passed along.

After changing the distributor cap rotor button plugs and wires due to a miss the car cranked up and ran 15 minutes then shut off. i now have no spark from the cap to the plug wires. any ideas?


It sounds like something is improperly installed or broken under the distributor cap. Take the cap back off and check for damaged/misaligned/broken parts or electrical connectors that are loose. If you see nothing obviously wrong, the igniter may have given up the ghost. This is part of the distributor assembly and you have to buy a complete distributor to get it. The igniter can be destroyed by improperly gapped plugs, a broken or damaged cap or rotor, etc.

2005 explorer 4.0 eng Service eng. soon light came on took it to autozone. The computer said #5 cylinder missfiring. Put new plugs & wires didn't make a difference. Checked compression this morning...


Changeout the rotor button and cap. the cap has carbon pins under there and wear down from the rotor button. The rotor button sits on the distributor which is easily pulled off. When removing these be sure the plug wires stay in order, Also, use di-electic grease on the plug wires, prevents moisture getting there and run away sparks. CAP/ROTOR button $20 approx.

96 jeep cherokee, inline 6 4.0... runs fine... after shut off (5-10 mins) acts like its chokeing out, wont start acts like its missing, no combustion (fuel injected) let sit for 20 mins, fires up fine......


Try the pick-up coil that is under the distributer cap.Remove the cap and rotor button then remove the plate that is under the rotor button.Next you need to take off the relucter wheel that is in the way so you can take out the bolts and remove the pick-up coil.

Car wont start


do you have spark out of the coil into the cap? if so i would suggest removing the cap and testing for continuity between the center plug (coil input) and the spring loaded button on the inside also check the rotor, if you have no spark from coil at all be sure you have it wired correctly and be sure the coil wire did not get pulled apart in the ends please rate -jeff
