No codes car thinks its all ok it starts rough then 60 sec smooths out. acts as if the timeing is reaaaaly off under a load (engine pulling up hill high gear) otherwhise runs kinda fine i guess? also put new plugs in w perfect .5 gap like it asks and im guessing theres a sensor that adjust the fiering so i dont need to mess a that right ? ( no distributor so...) Also when im siting at a light it idles rough e very few sec( 7-12) so its not consistent not every time the crank goes around or reaches a certain piston its just random. a friend told me its prob electrical so i guess whires or o2 sensor? i will buy and return a new set of whires see if it makes diff if it works il keep them but im broke and scared basicly bc i cant afford this :q:q:q:q.
PS i pulled each spark whire out individualy and it made a consistent diff obviously so that didnt seam like it but could still be bad whires conection right? Please anything u can say to help me would be great need help soo bad local cady asks 100$ just to look at it i bust my ass just to feed the northstar

It could be a number of things but I would check the following:

1. Fuel Pressure Regulator
2. MAP sensor (which should throw a code if defective; Anyway, disconnect MAP sensor harness and see what happens on cold start)
3. Coil Pack may be defective (spark plug wires connect to coil packs)
4. Possible leaking fuel injector. When you start does the engine run very rich or do you see white smoke?)
