I'm 100% sure plugs are gapped correctly and yes I have NGK plugs. I have been changing the plugs on my truck for over 12 years. I just cant figure it out!

Would the new pugs/wires/rotor require a Timing adjustment?
Did you use cheap plug wires? A guy on TRS.com used cheap plugs on his dual spark Ranger, and where ever the wires crossed or touched, they would short out. so check to see if your wires are touching, maybe use some well placed spacers.

I used NGK wires. The wires are not touching. I am going to get the timing looked at. Thanks

Timing lights are about twenty bucks at harbor freight.

Something is not clear here. (Jessie) Did you say you put the old parts back on and the truck started running right again? You said it ran 'the same', but I can't tell if you mean it ran the same as it did before the problem...or if it ran badly after you put the old stuff back on...

If you mean it ran okay after you put the old stuff back on...you have defective cap/and or rotor.

If you mean it STILL ran the same (like crap) AFTER you put the old parts back in...maybe you created a vacuum leak somewhere while working on it. I will assume you didn't pull the distributor while you were doing all this work. If not....it probably is NOT the timing. You can't alter your timing by changing plugs, wires, cap, or rotor.

If you have a 1990 you should have direct fuel rail injection, not a throttle body injection system. I was wondering if it started running badly AFTER you ran the Seafoam through it. It's possible you dislodged some garbage in the fuel system...PAST the fuel filter...and clogged an injector or two.

Thanks guys for the advice, it was the timing! The guy at Autozone gave me a mismatching cap and rotor (hitachi and mitsubishi). When I inspected the rotor I noticed it rubbed on the cap. I'm guessing that's what messed up the timing.

Your profile shows you own a Jeep Wrangler. With information like that, it's possible that the guy at Autozone gave you the wrong parts.

The guy at autozone gave me Nissan parts, just mismatching brands.

I was messing with you.

Probably should have added a LOL to the end of the post.
