guys i did the sea foam thing to my truck to see if it would improve my mpg (11.5) my truck now only stays on if im driving it or have it on D (drive) as soon as I put it in P (park) the rpms start bouncing around from 800 - 400 till it eventually shuts off. I noticed that if i unplug the brake vacumme hose the problem goes away...

any ideas?

 

make sure the vaccum hose is properly put on both ends...could have came loose a little just try it again and if not try disconnecting the negative side of the battery! basically negative battery disconnected for an hour is the auto reset button!

 

Thanks will let you know

 

hey man just wanted to let you know that it worked, thanks alot but now it seems that at idle my rpms are much lower than before. at idle im between 600-700 as before i was always near 800

 

thats fine mine nothing to worry about does it run fine and stay running?

 

mine idles around 700-750 or so

 

its stays on, but if im driving around 70mph and put it on neutral it shuts off.

 

uhm can i ask a dumb question? why when your doing 70mph do you put it in neutral? lol?

 

I dont normally do that, but since i knew that at idle the truck would shut off I wanted to see if the truck would stay on neutral.

 

oh okay...well idk man anyone have any ideas on why this is happening!?
