Engine has been missing for the last year replaced plugs, wires, coil pack, and #1 injector. It started using coolant and the heater would blow cold sometimes did a cylinder leak down to check for blown head gasket found # 1 cylinder blown. Dissasembled engine had heads resurfaced and pressure checked reassembled engine and it runs alot better than it did still misses some times when at idle and cuts out going down the road at 40 to 50 mph occasionaly. No engine light on before doing the head gaskets it was on all the time and showed cylinder #1 missed on several occurances. Rechecked all plugs and wires. Cut out cylinders with scanner and couldnt find source of miss. Please help thank you

Check the fuel pressure. Also check the oil for a milky substance, (Anti-Freeze). See if exhaust has that sweet-ish anti-freeze smell as well.
