integra sir-g idle problem
well there all maybe somebody can help me, i recently bought an 98 spec sir-g integra, i am putting all the running gear into my eg that i bought, recently the teg engine idles very low when started from cold and gradually builds up to about 1400 or 1500rpm as it warms up anyone have a solution for this before i rip it out i want it runing perfect.. thanks

Re: integra sir-g idle problem
does this engine utilize a FITV?
try this; remove the air cleaner boot. if a FITV is present you will see 2 ports in the throttle body bore. the top one is iac. the lower is fitv. stick a piece of tape over the top passage hole. this will block off the iacv and isolate the fitv. now, iac blocked and engine cold, start the vehicle. if the surging goes away, problem is iac related. if not, problem is fitv operation. probably sticking. because those are the only 2 places the engine recieves air with the throttle closed, it's easy to isolate and figure out.
try that method out. see what she does
if there is only one port, the ecm uses the ect sensor to determine iac position for fast idle. if that's the case, test resistance of the ect SENSOR (not sender, not switch, but sensor).
test first cold, then hot. the sensor will be an NTC (negative temperature coefficient) sensor. it will read high cold. somewhere in the 10Kohm range. and will drop rapidly when hot. somewhere in the range of 10-50 ohms. the spec isn't that important. you'll know if it's acting up. it'll be way off

ok so i had a look at the teg tonight there is an after market pro series intake manifold on it and there is only 1 port in the throttle body.. i took off the idle control air valve and somebody has blocked the 2 holes in it with window bond would this be my problem do you think. didnt cheak the sensor yet.
