i was just wondering if anyone has a quick and easy way to check for vacuum leaks on my 302

 

get out the propane torch dont light!! it but turn it on. then start the truck and run the propane torch any every posible place there might be a vacuum leak and listen for the engine to rev up when it revs up you have found the leak

the engine just burns the propane like it is regular fuel and it wont hurt the engine

 

thats a good idea never would have thought of it, but my problem is i cant get it to idle so i dont think that would work or would it? thanks

 

if you cant get it to idel the propane idea wont work what year is the truck and is it efi? if it is check the idel bypass valve if that valve isnt operating properly then it wont idel at all

 

oh i totally forgot about that bypass valve, thanks thats probably the problem, i hope
