Tach jumping, engine missing, me pist

[badstang123]

I recently had an array of electrical issues. First it was the alternator and then I began having other problems (Maybe related to a terminal on my optima shorting) Just thought I would fill you in on what fixed the problem if any of you were to run into the same symptoms. I had a power drop off after 4500rpms, a slight miss, as well as a jumping tach. After changing the coil, power came back but I still had a miss and a jumping tach. Next I replaced the spark plugs and still had a miss and jumping tach. I also tried switching out the TFI but it made no difference. Today I changed out the fuel filter, pcv valve, and plug wires. Everything is smooth as silk now. I have to figure a plug wire was arcing. I never thought a plug wire could throw the tach off like that though. Hopefully this helps someone who might have a similar problem at hand. :SNSign:

Guys, I think he fixed it and was just nice enough to post the solution for future searchers.

The distributor is new. Regardless the car runs fine now. I was just letting everyone know how much havoc a bad plug wire could do.

about two years ago I had the same issue...tach would bounce from idle on up...though there was no noticeable SOTP surging. looking at the tach pissed me off enough to get new wires, and everything was gravy from then on out. Glad you got it fixed...I drove around like that for weeks before I finally did something about it

You know what the sad things is though. People are just going to ask in a new thread instead of using the search button But hey, I guess that is what we are here to do. Help each other out with our common interest. :SNSign:

LOOK!

CHANGE THE DISTRIBUTIOR!

if not when it gets worse down the road and it gets worse you'll wanna burn the car down. I know I just went through all that.
MSD dizzy! I love mine!

 

[badstang123]

To reiterate. I was only telling people what presented a solution for my car. It's running fine now. I was just trying to help other people out who may have the same problem. If you guys are going to respond effectively you should really read the posts thoroughly.

ok to make myself perfectly clear. I had the same problem. the plug wire was only temporary fix. The car started doing it again a few weeks later. So if your car starts acting up like that again change the dizzy. If you car has high miles its gonna crap out on you sooner or later unless you get lucky. That help?

 

[95WhiteVenom]

sorry I missed that you had a new dizzy in the car.

[badstang123]

Lol. I'm glad we finally got that all worked out, because I was starting to get annoyed.

[Rainman voice] Yeah, definately the strrrrrruut bolts. Resonance frrrrrrrrrrrom loose suspension anchors. Orrrrrrrrrrrrr maybe a loose driver's seat. Yeah, loose seat track. Definately.[/Rainman voice].

Try those things and post back with any improvements.

Oh, PLEASE be sure and post on the thread what the fix is so future searchers can find what helped your issue.
