ok i had a pp 96 mm intake and i swaped to a fast 102...kept same 102tb and 100 maf and cam but i got my patriot heads ported and took off power steering and power brakes and added electric water pump....i finished it and fired it up and it fires right now but idles for 2 seconds and shuts off...of and i took off the evap canister and plugged that .....i cant imagine its all in the tune?????? it shouldnt of changed everthing that much....im assuming its a vacuum leak??? but how do you do a vacuum test of the car wont idle.....or do you think its in the tune ????


HELP

 

I have used a pump from a one man bleeder set that has a gauge and hooked it up to a vacuum line and pumped it to about 10 and seen if it bleeded off.

 

I worked on a car that did the exact same thing and it was the VATS (vehicle anti theft system). I turned the VATS off in HPtuners and it ran fine. Nothing you did should have messed with the VATS but it may be worth looking into.

 

thanks guys it was actually just a mis communication with the maf sensor took it to get tuned on a whim and it was all good went to a sd tune anyways
