I have a 1994 Chevy S10 pickup, 4.3L engine. And I put some slick 50 engine/fuel cleaner in it and filled up the tank with gas. Every thing was great, until I backed up over a bump and then shifted to drive. When I did that, the truck jerked. And now, it's running rough.
When I go down the street, it's hard to pull gas. The truck hesitates a bit. I'm not sure if I cracked a valve or maybe something else.
Where can I start first?
