I keep getting the check engine soon warning on my 94 Sonoma, 4x4, 4.3, 5sp. It only comes on after about 30 to 40 minutes of driving. The temp is good, oil pressure is good, oil level seems fine but it's hard to tell exactly because it splashed up the stick real bad. When I shut the truck off it resets immediately and I can go another 30 to 40 minutes before it comes on again. Anybody heard of this before. Brian
