Lol, I bought the truck with the spacer, as long as it is not negatively impacting me, I'm going to leave it on, I like the red gleam in the back of my engine. Just dug up some 10 gauge wire and some ring terminals, time to go put it on. Will post results, just drove to Taco Time and back so I have a good feel for previous levels of throttle sensitivity. I will throw in at red lights I was bumping around a bit on RPM's, which I hope this will fix.

Just as a side note, it is my engine that was perfected over time into your late model engines, so for all the crap I go through I believe that I should be entitled to something.

Edit: Well this isn't happening until tomorrow, I lost my socket for the throttlebody and I don't have the warmth nor patience to find it tonight......I also have homework.

 

Grounded my throttle body yesterday. I noticed a slightly lowered RPM rate at idle (600 vs 700). I also noticed a much smoother shift going from 2nd to 3rd. Acceleration actually seemed a bit faster, probably due to the smoother shifting. Haven't got it onto the highway yet but will report more when I do.

 

i just did it the other day.

MUCH smoother running and idling. i used 6G ready made wire from wallyworld for lawnmowers. cost was about $4/5.

 

I spoke to an Electrical Engineer today about this and inquired about the wire size. He confirmed what i had suspected, their is no need to go with anything larger then maybe one size bigger then the wires in the connector now. Likley 16 Gauge. So 14 gauge is plenty. The only reason for going with the larger size would be the distance to the ground point, but if it was say right above the engine on the firewall, then you could use the same size. His comment was "Have you ever seen an applicance with a positive and negative cable of two different sizes?". That alone proves the point. He said a Multi Meter will prove it. Use the same grounding point on the truck but then try wires of differing gauges but no smaller then the size of the gauge lead and see if you get different Ohm readings. At the voltage and amperage used in the TB, it will not make a bit of difference.

A chassis ground cable is very large because it carrying multiple sources of power. But most engine components draw very little Amps.

 

Well I did it, used 10 g wire, hooked up easily, took about 2 minutes. Had the engine warmed up already, so I tested it immediately. I was suprised to find that my idle was much more steady, and the truck shook less at idle (probably a timing problem, but partially fixed none the less). I also found the shifts to throw in a bit harder, which I like. Not sure if there was an acceleration improvement, but like hammer said earlier, the idle was worth it enough to leave it on. OP, you can change the first post to include 2002 & up now!

 

I finally got the ground wire from wally world. put it on sunday am. have to say it works just fine.can tell in the tranny this am going to work was no hesitation from 1st to 2sec.
throttle was a lot more peppier also. very happy with it over all.

 

Will this work with 02 1500 with a 4.7

 

No, you have a traditional TB which is controlled by a manual cable. You won't suffer from interference or grounding problems...

 

I can't believe that no one else here has anything to do with the ricer world. This is an old, dyno proven trick to them. Check ebay for grounding kits, you'll see tons of them for cheap. For best results: ground each head, the block, intake, and throttle body. (the ricer kits won't have enough for both heads, they only have one. Our plastic intakes can't be grounded, try the fuel rails instead.) Even on the 4-bangers power and fuel economy improved and has been proven on the dyno repeatedly. They noticed grounding just the fuel rails increased performance some 10 years ago or so.

 

I was having major issues with my throttle response('04 Hemi)...not really major, just majorly annoying. At low speeds it'd be easy to have the rpms "jump" up and down like it didn't know what it wanted to do. This would mainly be at low speeds, like driving through a parking lot or something, where you'd barely have your foot on the gas. But, it could also be noticed at higher speeds, it's just masked a little for whatever reason.

I also noticed that when I'd let off the gas, my RPM's would drop way low(600-800), and then bounce back up to where it should be if you were coasting in that gear. The response of the throttle was also off. It was missing that initial response when you first hit the gas, so you had to be very cautious at launch so that you don't make it jump at first.

All in all, I had been dealing with this stuff for about 4 years...just never bothered to get it check out because I had kinda lived to deal with it. But, I did a simple google search and came across people recommending to ground the TB, so I figured I'd give it a try(I'm an audio guy, I have a ton of wire and goodies sitting around). I spent all of 10-15min doing the extra ground, and....


EVERY PROBLEM I HAD IS GONE. NO JOKE.


This works, plain and simple. If you have an '04 Hemi like me and are experiencing the same issues, DO THIS SIMPLE MOD. It is literally a night and day difference. I don't have to think about how I'm pressing on the gas to avoid my old issues, I don't have to worry about looking stupid with my truck's erratic coasting at low speeds. It has all been fixed thanks to a simple 2-3ft long 12ga wire.
