I havn't pinned down if heat has anything to do with it yet.

you knwo how your car always starts the same way everytime, well mine is being a bit werid now... it starts everytime just sometimes will take the normal amount of time.. maybe a bit longer, or maybe even FASTER.

its werid

i guess the things in line with this are

fuel filter
coil
that chip thing on the coil

anyone else have any ideas?

Do a fuel pressure leak-down test.

how do I do that?

hook a fuel pressure gauge up to the schrader valve at the back and see if the pressure drops after the car sits?
