I have a current issue that happens like 10 times a year were i get a surging idle and it's always cause my fast idle valve gets dirty and has to be cleaned, I found a KMS block off plate on ebay for $25 shiped and my shop said that it would solve this common problem.

Now my question is, is there any downsides to using a block of plate?

Anyone that use's these give me some feedback thanks

 

Do you live where there is a winter? If so don't remove it.

It adjusts your idle to adjust for cold temps... w/o it the car will idle like crap in cold weather and or not start.

 

Doing regular engine oil changes and using synthetic oil may reduce the frequent need to clean the FITV, as well as the IACV, IM, and throttle body.

 

when I swapped my intake manifold and throttle body, the set up did away with the fast idle valve. I had to basically extend the hose that runs into the motor. Its been a constant 5 degrees in the morning here. I haven't had any cold start up problems without it.

 

i fab'd one up for my gsr and i haven't had any problems yet, and i can run out in the morning start it up and go back inside to let it warm up and it only takes about 5-10 mins to warm up. and its about 28-40* here in MD. just becareful taking the small bolts out of the bottom, if they have never been taken off alot of times the threads are dirty as hell and need some lube. not all the time but it happens.

 

yeah so i had one of aluminum cnc made for it, for 30 bucks came to 70 in all for labor, no cold start issues idles perfect, no more surging, very happy. I guess they do it to all there cars at the shop

 

what do you do with the coolant line that is left after you eliminate the FITV with this block off plate?

I will check it out tommorow and post it up incase anyone else is wondering ill also takes some pictures of the set up so theres info and pictures on th is for some tech.
