need help please
I have an 89 s-blazer with a 4.3L, auto, & 123000 miles. My problem is that sometimes when I leave a stop light it acts like it is only running on 2 cylinders. When I push the gas pedel to get up a hill (even if I'm running 70 mph) it starts to cut out like it has a bad miss. I changed fuel filter, TBI base gasket, cap, rotor, coil & I'm going to put plugs & wires on this week. Has any one had this problem before. I was told that it could be the lock up converter but it acts like a ignition or fuel problem to me. Thanks for any help.
