I can pull spark plug wires off #1,3,5, and there is no difference in the engine. #2,4,6 seem to be the only ones working. I have replaced the fuel filter,1 injector that was not working but now 2 more cylinders are not working.Today I changed the cap and rotor. The spark doesn't seem quite right. The cat converter is 265 Degrees on the drivers side pipe and 110 on the other. I disconnected the header to see if it would run better without any exhaust pipes. No such luck.I can get my injectors all checked for $100 locally but I'm not sure it's the problem.It started on the way to work 10 miles after filling up with gas at a busy station.Any help would be appreciated.
