well my truck hasnt been running right for about 3 weeks now and i thought it was the ignition so i replaced about 200 dollars in parts that didnt fix it. it runs fine but i have to be easy on the throttle or it loses power and it shuts of at idle. i checked my oil yesterday and it was really thin and there was bubbles on the dip stick. it smells like gas really bad so i changed it and it ran really bad but its fine now. im gunna get a compression test today but i think i blow a head gasket. Anythink else it can be.
