What position is your fan switch on? If your low on freon and have the fan switch on " feet and front(face)" it will do that untill u refill the freon and disconnect the battery for a few minutes.

The mistakes he made were from autocorrect. It tried to put in the same words while I was retyping it.

 

Lol u got it. Unlike these lame *** fools tryin to talk ****. Haha get an iPhone or iPad an ull learn to autocorrect ur reading thanks for the back up lol

 

Just bustin your ***** there Susan calm down don't let your keyboard get ahead of you

 

Come on guys. No arguing lol everybody just take a breather I mean it could be worse you could be driving a Chevy....lol

 

Never happen !!

 

Hahaa.

 

Could it also be a fuel pressure regulator ??? Or is that part of the throttle position sensor and all that stuff ? Im used to working on less complicated things with a carb sitting atop the motor not a funny lookin little throttle body with sensors all over it lol

 

Hey so I did try something in regards to my fan switch. When it's turned on face/feet or ac. Is when it revs up and wants to go but if it's all the way turned on off position it idles normal. How do I fix it do it idles normal regardless of fan switch??

 

Well mine would idle from 4-700 rpm befor I refilled the freon an reset the truck by disconnecting the battery. I thought it was an idle controll or something like that but when the freon is low it makes the truck idle funny. Even with the ac off it would still idle up an down when the setting was on any option except face an except feet. But all other settings runs the ac compressor. Oh I also switched the ac cycle switch. 15$ an it is an easy fix. I hope this helps cuz I didn't quite understand ur exact problem. Try this an lemme know if it helps. A total of 60$ or so an an hour of time

 

The ac will cause a surge from 600-800 only. If its going above 1200 rpms, you could possibly have 2 issues. One could be a vacuum leak. Most commonly from the large PCV elbow on the back of the upper intake manifold. The second thing would be a dirty throttle body, and it leads to a sticking throttle body, and a sticking idle air control valve.
