I took a look this morning and could not find the ground.

Online, I found a guy with a 94 GMC 1500. Like you said, he found his ground connected on top of the frame. It was under a electrical connector. I'll probably have to wait until I get the bed off to check this ground.

It's still throwing the code P0300 "multiple misfire detected".

I ordered new plugs and wires. Hopefully that will work.

Don't forget to check for a clogged injector also.

Ooops. Thought it was v8. The v6 doesn't really have injector problems like the 8's do. They have a spider type tbi injection which has it's own problems.

I think you're right Ron. It looks like lots of people change it to this: http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1

I don't really understand this, but a lot of comments on it are like this one:
Quote:
replaced my stock SCPI (Sequential Central Port Injection) with this MPFI (Multi Port Fuel Injection), this works much better than the old system, and is "plug n' play". It has the same Multec II as Corvettes, etc. It bolts on with no changes.

Plowin like a champ Frank!

I plowed 3 times and no codes.

Then on the last time, I went to get out and like a moron, forgot I had a standard and stalled it. Then it threw a multiple misfire code.

I got spark plugs, a dist cap, rotor and amazon injectors ready for temps above 40. One of these friggin things will hopefully fix it.
