I have a 1995 C1500 Chevy with the 4.3L V6 engine. Its a TBI engine. The other day when I started it for the first time in the morning it skipped and miss fired really badly for about 30sec then it was fine. I used it all day and it started up normal every time and ran perfect. Then the next day after it sat all night it did the same thing as before only for the first start of the day then it was fine all day again. It sounds like its only firing on 4 cylinders when it miss fires. I have new plugs and wires in it, new fuel filter, cap and rotor. Also the fuel pump and strainer are only a year old. I checked vacume lines and they all seem fine. My personal thought is that it might be a bad ignition control module because it only does itonce in the morning then its perfict the rest of the day.Any ideas? Thanks for your time and help all!
