Car bogging til warmed.

[mitsuclipsegsx]

In my 99 gsx, it boggs til it warms up. plugs are gapped at .28 ngk 7es, accel wires 1 yr old(did sit for winter) 1yr on 02 sensor, what could it be?

I had the same thing happen to me this winter. It just went away with the season. Sorry I can't help.

yea, its been doing it for 2 years, not bad cause after 5 min of driving it goes away, just wondering what it is...

Do you let the car warm up before you drive it?
I have the same problem with my car. It runs like someone unplugged 2 spark plugs or something, then after 5 or so mins it goes away.
I cant remember the name of the sensor that controls it, but if it goes bad warm up enrichment is turned off, therefore making your car run richer than bill gates for a little bit.

Coolant temp sensor?

I had the exact same problem, and when I tested the ISC found that it was bad. I replaced it and have never had the problem since. Now I have a new problem , idles at 2000 RPMs. But I still suggest testing the pins on the ISC and make sure it is working correctly.

fast idle air valve or coolant temp sensor.... also the idle speed controller could be a problem.... everyone in this thread pretty much said all the answers already... that I can think of

Where is the fast idle air valve located?
