I having a major problem hope somone can help. My S10 blazer is running like ****. I have ti pour gas into the throttle body too just get it started. When I trun the enginge over it just cranks over and over I had the crankcase sen. replaced and the sensor under the destributor cap replace and change the feul filter. I can get it on the road but as soon as i put a load on it it dies. hope somone out there has had this problem and found the answer.
