i have a 1999 Chevy S-10 4x4 5 Speed 4.3L.

My truck in the mornings and on rainy days runs like shit, i misfise badly!! Is anybody else having problems with there truck. I have replace the plugs, wiring, rotor and cap twice and it helps for a little bit but go right back to doing it. It does it all the way up to running temperature and it still does it after being running for 15 minutes. Thanks.

Look for sparking from the coil area at night.

What do you mean by misfire. My 95 blazer 4.3 seems to bogg/buck on inclines and bumps if i keep it at a seady throttle. Do we have the same problem?
