Tune up question help is needed
 

I have a 95 gt and just got plugs, wires, cap and rotor. I was wondering the gap size on my car. Ok another thing last night my car was acting up it would start then choke out i put 93 gas in it at a cheap gas station could that of done it I fiiled it up after that with 87 and it runs fine thanks

I beleive it's .48

Also if you don't have your timing bumped up more than stock, not running a chip for 93 octane, then your car could be running like crap due to the higher the octane rating (93) the harder for it to combust.
If you do have your timing bumped, say 16 degrees, and you put 93 in it, then the gas is bad.

anywhere from .044 to .054 should be good. i have mine set at .052
