Idle Issues

[Mrcln1]

Still having issues with rough idle, sometimes dies after start up, and surging. P0171, P0171, and misfire cylinder 4 codes. Replaced throttle position sensor. I thought the plug on the left side of the throttle body was the map sensor but when I got home with the box it looked different. All the pics of the map sensor on the net look like what the gave me. Whats the plug on the left side of the throttle body and where is the map sensor located?

If replacing these doesn't fix it I guess the fuel pressure regulator is next. I cleaned the maf but I guess I could replace that too. Just wanna get it fixed so I can get rid of it. I'm gonna loose my butt on this thing. Just wish I could keep the seats. lol

Thanks,

Mrcln1

x3 - a definite possibility!

Cleaning the MAF may not help if it's just plain old fried. If you run an oiled filter (like a K&N) then the oil could have fouled it. Some people have had luck with cleaning when that happens, others have not.

Good luck!

Please try cleaning the Idle Control Solenoid first... If it's the culprit, it's an EASY fix!

I run a regular paper filter. I tried spraying around the intake to see if the idle would speed up and it didn't. Wheres the map sensor located? I'll clean the idle control now.

Thanks,

just cleaned my idle control solonoid.. need a T20 torx screwdriver to remove it.. the screws on mine were pretty stuck.. best way to do it was to stand on the passenger side of the vx and put your weight behind the screwdriver to take them out.. cleaning was easy though, make sure to get that O ring too

I sprayed the idle control with electrical cleaner yesterday when I thought it was the map sensor. lol I didn't try pushing it in or seeing if it moved when running. I'll do that tomorrow. So where is the map sensor located? Since I have one I might as well replace it.

Thanks,
