Question about 2003 Chevrolet S-10

1 Answer

After my truck (2003 S10, 4.3) sits after running it for a bit, start it and it will start missing and the check engine light comes on. The miss will go away after about 5 minutes running and the light goes out. I found a small puddle of anti freeze under the truck and looks like a small leak in front of the intake manifold. What can it be? I have 2 ideas of what it could be. A head gasket or manifold gasket.

Intake manifold gasket. when it leaks water will enter a cylinder causing the sprark plug to short out. when the engine gets hot enough the water will cook off in the cylinder allowing spark to take place. 80% chance intake manifold gasket, buy the upgraded part. 20% chance head gasket. Take the intake off and check for broken intake manifold gasket then buy parts.

Does the miss quit or does the engine quit. If it misses for a while and then quits missing, you've probably got a fouled spark plug caused by oil fouling the plug after the engine sits a bit. The root problem is leaky valve seals. The quick fix is try new plugs.
