Vacuum leak question
Have a 93 gt engine with e7 heads, 1,7 svo rockers, stock injectors, stock MAF,
70mm edelbrock tb and elbow, trick flow intake upper and lower manifolds,
Mac shorties, bbk cai, msd pro billet dizzy, mad 6al2 box
Originally set it so car idles at 900rpm,
When the engine gets to temp and I either drive it or rev it, the engine only comes back too 1100rpm..
I was told this is the sign of a vacuum leak and to use the propane from a torch to find the leak.
Whatcha guys think?
