My injectors ohm out at just over spec. 15 to 16. Would this case the misfiring i get? It dose not happen all the time. but when it misfires it gets bad. 98 4.0 with 230k miles.

 

I don't think so. Plugs have been gaped to .035, cap, rotor and wires are clean, look good. I don't like AC plugs, posters have had issues with platinums. Champion copper and NTK ....seem to be the ticket.

Guys who know your Jeep better than me, might ask, what codes it has stored, and more about "misfire".

If you now something might be up with the injectors...there IS a number on the side, that might help...were they changed,,,they might want to know.

Anyway, even Programbo might like some of these links!
