I have a 91 Accord EX coupe with a 2.2 F22A4 and it recently started missing like crazy. My first thoughts were bad gas as it happend not long after i got gas at a cheap place i dont usually use, so i filled up with 93 and a can of seafoam thinking it would fix it. well its been about a month and its getting worse daily. I have replaced.....The Distributor, Distributor Cap, Rotor, Plug Wires, NGK Iridium IX Plugs and ran a can of Seafoam straight through the vaccum system and nothing has helped at all. I am a manager of an Advance Auto Parts Store so i hear peoples problems and help solve them all day every day but this one is gettin the best of me, also the fuel filter was replaced about 6 months ago..........Any ideas?????? Thanks

 

first off find out which cylinder is misfiring ,if misfiring on 1 particular cylinder and you are sure that plugs and wires are ok, , chk to make sure that all injectors are working properly,if injectors are ok,, do a compression test ..did you adjust valves before ?? also unplug the hose going to egr valve see if that helps ..

 

Plugs and wires cap and rotor replaced yesterday. i will check those other things and get back. thanks

Also what should the compression range be on this motor?
