i recently purchased a 1987 305 iroc z w/tpi. what's the correct way to set the timing? also, car won't crank when it's cold; if you hold accelerator pedal down about 1/4 to 1/2 inch it will crank. i'm a 60's and 70's chevy guy, and this is my first computer/tpi car i have owned so be gentle. thanks for any help.
