have any of you had problems starting your car after it sits for about 15 minutes after its been up to full running temp for a while (hot starting ) my car will fire with less starter revolutions, but thats all that happens, it fires, i have to let off the starter cuz its just like it started, but it doesnt stay running, i havea 94 auto 5.0 with stock heads, cam intake, i have messed with the timing a little, i set it with a light to 15*, but it pinged a little, so after i gave the light back to my buddy, i had to back the timing down a little till it didnt ping, im sure it ended up around 12-14*, and dont even know if this is whats causing this problem... my only mods so far are march u/d pullies, MAC CAI, ford racing cap-rotor, taylor race wires, and MAC cat-back... not a big deal, but its embarrassing when you want to look bad a$$ in a crowd and your car doesnt start... hehe any help much appreciated
