Car Starts Good, Runs Good, Then Misfires After Warmup

[MrAl]

Just try removing and reinstalling the number 3 plugwire first. At night, look for spark misfires between the plug wires and the head with the cover off, too.

If the plugs are that old it is a cinch the cap and rotor are old and crusty too, that will cause single cylinder misfires.

OK thanks ill try that first.
If not i guess distributor and rotisserie

What Abscate said. Re-seat plug wires and coils.

Correction to my post…

Coils should be singular: coil. Sorry about the confusion, if any. I need a periodic reminder of the single year 98 that were still mostly mechanically an 850.

No problem Matt i know some have one coil per cylinder lucky mine only has the one.

You can get to the cap screws with the right length screwdriver and just the top off the air cleaner. It might be ugly in there if the seal has seeped, all full of water and oil detritus

Hello,

What is that taking off?

I think it's ok now after changing the #3 spark plug wire. Ran good all the way to the dollar store and all the way back.
Knock on should

The distributor cap. Mine was dirty in there, a bit. I cleaned it with brake cleaner, the first time I opened it up. I cleaned all the contacts with a wire wheel on a Dremel tool. That helped quite a bit, but then I went back later with the new parts we've already talked about.

Oh, I did that yesterday.... bought some scrub brushes, and a bottle of LA's Totally Awesome cleaner. First use might be on floor mats.

Hello,

Oh right, yes the distributor cap. Thanks.

Oh so you are a dollar store fan too? I've been going to those places for decades now. We have a couple Dollar General stores around here i go to quite often. We also have a Family Dollar and a Dollar Tree, all within less than 2 miles of here. That's four dollar stores. We also had a fifth one dont remember the name of it now but it was also about 1.5 miles away, but that one closed up some time ago. We also had a Radio Shack about 1.8 miles from here that moved to the mall about 6 miles from here, then moved back to town some years later about 1.5 miles from here. That was until they all started closing up. I hear some might come back though not sure if it is just a rumor or not yet though.

Yeah the dollar stores have good prices on so many common items like brushes and cleaners and you name it. They also have food products that are not too badly priced although within the past year or two the prices have gone up a lot. A gallon of water used to be just $1 now it is $1.50 which is a 50 percent increase, which is hard to justify i think. I talked to someone in finance a while back they think it is because of the increase in the price of diesel fuel.

So i should be attacking the dist cap soon too see what is happening under there. I hope i can get that new #3 wire out without ripping the booty the old one was very hard to get out of the cap hole.

You can partially thank Warren Buffet for the increase in the price of diesel fuel. He lowered the amount of DEF able to be sent by rail. One of the customers impacted was Pilot, the major truck stop chain of which I live within a few miles of one of their locations. You and I might consider them to be vital infrastructure... This all started in spring... It's just now catching up with us. You know who isn't going poor in this? Warren.

Remember how the railroads claimed they couldn't afford unpaid sick time for railroad workers? They seem to have a hiring problem too. Who wants a job where the only way to get a day off is to die? So now their only choice is to walk away thanks to congress. I'm not sure what went wrong in this country that people cannot be guaranteed UNPAID sick time at a federal level. You would think we had learned the lessons of the pandemic, but apparently not.
