I have a 2001 GS430. Sometimes when in drive at a light if the a/c is on idle is fine if its off then a little low and rough. Well no more for me I purchased a Grounding Kit from Paul Kwan at TekKits.com , and its gone, tranyy shifts better, lights are brighter. For less then $80 bucks its great. The instructions are amazing so Easy from start to finish in 45min including removing and reinstalling the RMM Strut bar. If you have the Idle problem definitely Buy a Tek Kit. For $80 even if you don't have low idle buy one. Smoother shifts brighter lights. Thank You Paul.

 

I have a 2000 gs4 and also did the grounding kit and had it installed at TMEngineering. Still have the rough idle.

Glad it worked out for you. I guess for the price it's worth a try for those that has this problem.

 

Webpage not working but you think it made a difference ???

 

This is the page sorry www.teckkits.com

 

Your transmission will also shift smoother and when its supposed to.

 

so you're saying your idle is actually higher now? what rpm does it idle at now with ac and lights off?

 

Just under 600

 

that's where mine is at stock too. glad yours is better now, but maybe you had something else going on besides just the standard low idle in D.....

 

Do these really make any difference ???

 

Dino Its $76 bucks. I am sure you have spent more on lap dances at Curves. LOL What do you have to lose.

 

Don't waste on my money on ho's, lol they come to me, lol, but your prolly right about that price $76.00 bucks is cheap but i heard about something else my boy just got in his truck it something like a grounding kit but he says it feels like it pulls better now not sure whats its name thou...........Something that helps keep the power going to the engine, never heard of this myself......

 

CAN YOU POST A PIC WITH THE ENGINE BAY AFTER THE INSTALL?? i AM INSTALLING THE GROUND KIT MYSELF TOO BUT DON'T KNOW WHAT IS THE BEST PLACE TO CONNECT THEM.
ALTERNATOR, CHASSIS, THROTTLE, AND ENGINE. THAT IS ALL I CAN THINK OF. THEY SAY MORE CONNECTION IS BETTER.
plEASE HELP./

 

I just got mine installed too! the rough idle still there but much better.
and you do feel the difference!
