New here so be gentle!
I bought a 1995 F150,and I love it. But there is a problem. Between 30-60 mph the truck jerks and spits and sputters and the a/c shuts off. Then it smoothes out and the air comes back on Any ideas?

 

Wow...That's interesting.

 

Check or replace your battery ground cable.

I know it is very weird. Guess I will keep studying on it! She is my baby!!

 

That's something I never considered. I am lacking the knowledge of what effects what. Thank you, I will try that this afternoon!!! I hope that is the problem, will post the outcome. Can you explain why you think that could be the problem? I have no starting issues.

 

Good luck. Hope you figure everything out

 

Well I checked the ground cable and it looks good,and fairly new. Do you have any other suggestions? Does anyone have some help ???? I know there are a lot of great mechanics on here!!

 

Can you pinpoint it to an RPM range instead of a MPH? I am just wondering if you were to drop it into 1st and brought it up to 3k rpm if you would notice the same thing.

Sounds like you have a vacuum leak somewhere.

 

I don't have a tach in the truck but I suppose I can try that by sound?? I will let ya know.
