I had posted a few days back regarding a surging, jerkiness or bucking in my car that I noticed when the cooling fans came on high, either thru using the fan mod switch or having the a/c on.

After re-reading some of the relavant previous posts, I decided to add some extra ground wires. So far, it seems to have done the trick. No bucking or jerking.
(fingers crossed......)

 

It helped mine dramatically - gone. I made up a set with multi- stranded copper wire, then crimped and soldered the ends to copper connectors. I went from the battery to the front of the frame, firewall, alternator, intake manifold, rear engine hoist mount and chucked the stock ground strap.
I went pretty heavy gauge - probably overkill. What's really interesting is I also don't have "rotary rock" at idle anymore. Smooth...... weird though, because I can't really think of a good reason this would work! The only reason I did this was that I saw them for sale on a Japanese site and thought what the hell.........they called it a Grand Earth or something like that - and they wanted damn close to a grand for a few freakin' wires!

 

A while ago, pettit was giving away ground straps.

They may still give you one if you call and ask.

 

sometimes you will have to clean the area too.

 

I think Ill try using some old 4G stereo cable I had around to make some straps....Mine bucks when my foot is resting on the gas...Thought It was the tranny or rear end having play in it. Ill try this and see how it works...

 

Are you guys using the stock ECU or a PFC?

Ill try looking in the shop manual for the stock ground spots...
