My mom has a 2000 Eclipse that has been throwing a code for2nd cylinder misfire. It died today. I replaced the wires and fuel pump. I tested the 3 front wires and 2 were bad. Also checked the relays. Still need to recheck the codes. There are so many sensors and wires, its a little overwhelming. One suggestion could go a lomg way. Thanks.

 

Well did you check for fuel and spark?

 

2nd cylenders spark may be fowled, broken, plug wire bad, injector dirty, not working, throw gas cleaner, replace plugs and wires is the norm maintanance

 

I've now replaced the plugs, wires, valve cover gaskets, and tube seals. I thought it was just a simple tune-up because I tested two bad wires on the front and saw two leaking tube seals on the back (that I didn't test). Newer cam sensor, cap, and rotor. I'm thinking that I need to trace back to before the cap, but that's pretty much where my knowledge ends. Could be a sensor or something. I don't know.

 

So have you done this?
