Misses like it's drawing moisture.
This is on a '97 GMC Sierra. I'll give it a complete tune up and in about three to four months it starts doing it again. I've been around and worked on vehicles most of my life and this has me puzzled. I have heard it could be anything from the computer to the coil or even a bare wire. I hate to keep changing everything every couple of months, and, besides, I can't afford it.
