this happens only when the car has been driven for some time and at normal operating temperature.

When i come to a stop or in neutral the idle bounces but some times it does not.
other times it does idle like this and after a while it stops and when i give a little gas it starts again.

Note: no CELS either. temperature gauge isnt working but have a digital on on a pillar. this only happens when the car is running after a while and no when just started cold.

Thanks in advanced for all your input.

 

is your extra guage connected to the coolant temp sensor?

 

well according to the person I bought it from he said the temp guage never worked so he installed a digital one in place of it.

i have dont nothing to the car just purchased new suspension, and a cluster, header.

 

i will look into it all this week, I have most of the week off and most of the parts are comming in this week so I will look into all the wiring mess.

just never had time due to a busy work schedule constantly and college.

 

on most of the cars ive worked on that had no reading on the temp guage, and ran poorly, the coolant temp sensor had failed completely...i dont see why he would have installed an aftermarket one though, can you trace out how the other gauge is ran to get that temp reading?

 

it runs good just the idle just bounces like in the video only when the car driven for a few minutes. Engine is strong, now the header is dented pretty badly. I have a comptech one on the way.

Its literally a mess wire wise Im trying to find a local to help me out with the wiring configure.

the car has a chipped ecu and aftermarket cams installed would that effect the idle.

My intention is to get stock gsr and a virgin ecu just so i could get the car back to somewhat stock. Ill leave the type r sways and skunk 2 IM and pwjdm CF whale ***** intake and the exhaust. Just need to straighten out the idle situation.

 

yes the chip ecu can effect idle, i have the same problem but mine is caused by the vaccum hoses (im pretty sure) but my car also idles at like 500 too, which isnt good either and i also do have a skunk2 im. I would say get a virgin ecu too see if that is the problem my guess it is.

 

yes im looking for a ecu right now

 

my car does that all the time but my car is fully built with cams and everything is it bad?

 

i know what happend, it happend to my integra too, the problem is the idle controller, also when you fill gasoline, you should use the plus instead of regular.

 

Check for vacum leaks, also check pcv valve. It could also be the tune. Try a stock ecu and see if it change
