Idle sounds Like I am Gunning throttle

My truck has started doing this every morning when I Start it maybe 50 degrees outside. It did this once last year. Now It does it every time. It will gun up to 1100 to 1200 rpms and drop if you dont catch it with throttle I think it will die allthough I havent actually let it die.Does the truck have an idle control module or something that could be bad. Thanks

Mike

I have a buddy with a 01 that was doing that, I’m not sure if I believe it or not but he swears changing the CPS fixed it. I was guessing at glow plug system or the IPR but he said a Cam sensor solved his.

I got a new one on order they are cheap enough now to just try it anyway. I have been meaning to get a spare one anyway. The only thing is it did this right after replacing cam sensor last year once or twice.

Thanks

are you talking about the high idle. my truck will do the is if you let it set for a min while running while its cold out. the truck will got o 1200 rpm to help it stay warm. it will fall back to 600 rpm if you touch the brakes. let it go up its not gonna die unless you have another problem. i would have to say this is normal. it just seems like its gonna die cause you drop from 1200 to 600 rpm which is a big drop. mine does it all the time when its cold out.

No its not the high idle. It keeps doing it over and over again. Just like If I was sitting there gunning throttle up to 1200 rpms and drops over and over again till you gun throttle and sometimes that takes 2 or 3 times to make it stop. I dont get any codes. It also smokes pretty bad with smoke that burns your eyes. I cant tell what color it is I think its white. I just took it to a local diesel mech and he found a bad glo plug relay. It was bad checked myself but it hasnt been giving me a hard time starting so did not notice it. Still did not fix the problem. I am sorry so long but some help would be greatly appreciated.

Mike

White smoke sounds bad, I can't help you out there but mine idles up to 1200 for a bit when its cold and then goes back down to 600rpms in the morning.

Bump to the top
