Ok tonight I was on the highway and after driving probably about 12 miles i hit some bad traffic. Anyway it was bumper to bumper for about 2 miles. I would put the car in first gear go out 20 feet and push in the clutch and hold it in and leave it in 1st while i sat as long as we began moving again within like 10 seconds because normally at lights and stuff i put it in neutral. Anyway i would push the clutch in and as i came to a stop the car's idle would droppp very very low about to stall out. One time the CEL came on for a second and then came off as i threw it in neutral and gave it some gas. After that i put the car in neutral instead of just pushing the clutch in and it seemed to work better, i also turned my fog lights off. What could the problem be ? I drove about 12 miles at around 75 mph so the battery should have been fully charged. Any ideas ?

 

check ur IACV i had the same exact problem, so i found a new iac valve on ebay for like 30 bucks and it fixed that problem real quick..good luck

 

I just cleaned mine this weekend very well no leaks or anything.

 

Also temp gauge was reading normal

 

bump

 

my car did the same exact thing. cleaned iacv, fitv, tb and changed wires, plugs dizzy. nothing helped. atlast i did the complete egr cleanup(valve+ports) with seafoam. ran rough for a few miles. problem gone!

 

did you check to see what code it threw? that would be a great help.

 

well it threw a cel for like a second just before it was about to stall then i gave it alitle gas and it went away. The cel disappeared right away and hasnt reappeared. It was on for a total of about .01 seconds literally.

 

A bad lambda can do this. My H22 died in trafic several times before I got the lambda sensor replaced.

 

yea i am also not sure wut a lamba is ? I had a missfire problem a few weeks back changed the plugs, checked all the wires, cap and rotor....and the problem went away. I also recently changed the o2 sensor.

 

lambda sensor aka o2 sensor.

 

The o2 sensor is less than 2 weeks old theres no way. And i double checked the part number before i installed it so im sure its the right one.

 

I had this problem also. Mine threw code 17 which is the VSS (speedo was not working). I think it put it in limp mode or something but everytime I was at a stop sighn my idle would drop way down. I didn't fix it yet. I just turned the idle screw and have temporarily fixed it, runs well so far.
