I have a 94 Acura Integra Gsr, and lately it has been surgin from 1000-1500 rpm in the morning when its cold, now as of last night, it idls at 1200 and surges up and down from 1200-3000 when im driving under 2000 rpm and when sitting at a light, or just in netural.

Help!!
What can it be and what are the $$ estimates, where on the peninsula should i take it?

 

any cel on?

 

I.A.C VALVE (idle air control valve)... do it yourself, its not very hard.........

 

sounds like iac valve, pull it off and spray it out with carb cleaner, or you might have a vacuum leak. imo IAC valve

 

thanks i'll look tomorrow morn

 

any other suggestions, ok i got the iac valve off and have sprayd it down. should i soak it, leaving the plug out of the mixture or what.

 

could be a few things...but try the iac valve, egr valve, and pcv valve

also..whens the last time you changed/cleaned the air filter?

 

whats the egr valve?

 

Have you done anything with the idle adjustment screw or bypassed the coolant lines from the throttle body?

Do you have a Hondata?

Also if the throttle cable is too tight that can cause it.
A dirty sticking throttle plate can also give the same symtoms...

 

i agree with this........
