2 Real Stupid Questions.....
I have 2 questions that i am almost embarrassed to ask.
1) I am looking to tune my distributer (vacuum), my friend said hook a vacuum gauge to a vacuum line and loosen the hold down on the distributer and with the engine running turn the distributer untill the vacuum reads the highest. is this correct or is my friend wrong?
2) I have some glasspacks on my car and when i have the RPMs high and i let off of the gas it sounds like pop corn is this normal for glass packs? and does this mean i need to adjust my timing? could this mean i am detonating? it sounds really mean revvin up but when i let go it just goes pop..pop..pop..pop and crackles a lot
Forgot to mention i did a quick search for vacuum advance and couldn't find anything helpfull
