Idling wierd?

[SnipeRA]

I have recently noticed that when i am stopped at lights that the car is idling weird. Almost as if the car is going to stall out. It fluctuates between 750-500RPM. This has only started to happen after i swapped out the Front Mount with a stock EVO X and added an UR UICP. It seems if i out it in neutral and take my foot off the gas it helps a little. Less fluctuation in the rpm but is still noticeable.

Any idea why it might be doing this? Has anyone else noticed or had this problem.

Yes that will definitely solve your idle issue.
Tune is very important!
Save your money by buying all the mod parts you want & install at the same time & tune for last.
"Measure 10 times cut once"
Save you money on tune every time. IMO.
Tuning after every upgrade will cost you more in a long run.

Im collecting all the parts first, put all the parts in & tune.

This is my first new car as well as the first one i have worked on/ will be working on. I was told i didn't need a tune for FMIC and UICP upgrade. But i do agree and had planned on getting all parts first then tuning. Thank you for the feed back

I think when ever you upgrade any part from stock the car is going to sound and run alittle diff.... but thats just me.....

is it normal for RAs' idling to bounce from cold start at 1500 and warmed-up engine drops idling to 750 and still bounces? Mike at RRE says the idle is running at 6 different tables but it's normal for the needle to bounce...just wanted to know since I'm a turbo noob...just wanted to make sure nothing wrong w/ engine...thx guys
