Have a 1997 Mitsubishi Eclipse Spyder GS with a 2.4l. When it is cold it misses not bad but a little. Was really bad and i replace the fuel injectors and it was not missing then. Then a few moths later it comes back. He has took it to mitsubishi to be looked at but they told him then it was to old. After it warms up miss goes away. He has put plugs and wires in it. I got the injectors from rock auto the only place i could find them. New timing belt was put in to. You mostly fill the miss under a load. and like i said it is not very bad of a miss. Any ideas could help. I do not have the stuff to check fuel psi.

Any codes in the system to identify the cylinder?

Generally speaking, cold misfires can be attributed to cylinder sealing issues, over-adjusted valves and coolant intrusion.

P0302. Came i a about mouth ago with P0301 and put another injector in it. Now it is cly 2. Does anyone have a better place to get injectors

This is a really long shot, Rich is a great injector guy. I see he isn't going full steam any more. Maybe worth an email to him, he may be able to point you in the right direction, or fix/clean the ones you have.
