Re: 93 s-10 blazer
What engine?
Any check engine lights on? How is the fuel pressure? You might want to recheck the fuel filter. If a lot of water still in it run some heet/alcohol type stuff in the tank.

Re: 93 s-10 blazer
4.3 liter vortex, no lights, haven't checked the fuel pressure yet, but I will. could it be anything with catalitic converter or o2 senser? The gas tank was changed before I bought it

Check fuel pressure and recheck fuel filter.
Post back fuel pressure readings. Cat/exhaust blockage can be checked with a backpressure or vacuum gauge. MT
