Misfire

[subie bob]

So my lgt had a cyi 2 misfire i replaced the plugs it stayed away for about a week then came back changed the coil it stayed away a few days it wasnt running very bad had slight hesitation cleared the code and kept driving it for a few days. now im getting misfjre codes on cyl 2 and 3 and running pretty rough up to about 2500 rpm. Anyone experience this? And what can i check next to eliminate this problem?

Nothing?

Have you swapped injectors and see if the CEL follows them.

 

You can do the same with the coil packs.

 

Oh yea, make sure the connectors on the packs are tight. Some have found them loose.

I have not tried the injectors but i have checked the plugs on the coils. Ill try the injectors this evening

So no change switching injectors time to do compression test. Any recommendations on head gasket kits if end up needing to pull off the heads?

Have you swapped coils yet? If so, try the twist-the-pin-on-the-harness-coil-connector trick.
