CEL P0300
Greeting all, glad to find such a great forum, as a new dodge owner I am sure I will find a wealth of information on this site. Anyhow, here is the problem: Wife was out with the 2000 Dakota SLT 5.9 and came home saying it was running like $#%#, and the CEL was on. Did a change on the 02 sensors because I did not know what else to do; improved things somewhat, but still ran "rough". Bought a code reader today and am getting this:
P0300 (M) Multiple Cylinder Mis-Fire Misfire detected in multiple cylinders
Also getting misfire code in Cylinders 5,7,& 8.
Any suggestions on where to start?Thanks

RE: CEL P0300
I have checked the plugs, everything seems OK. Now being a stupid goof I thought I was pulling the PCV last night in the dark and managed to snap off the plastic breather tube connection on the passenger side valve cover instead.[:@]So guess I cannot really carry on for another day until the part shops open again on the 2nd. In the mean time would appreciate any input on the following:
MTN13 suggested I check the coils, would like to know the best way to do that.
The mechanics at work suggest I check for vacuum leaks by warming up engine, then run an unlit propane torch along line and listen for an increase in RPM. Is this a good idea? The boys are really only good for oil changes and flat tires, don't wish to blow myself up.
Thanks in advance for any suggestions.

I have been having the same problem with my 2001 v6 for about a year I and my brother have done a lot of playing around and the only other thing we can think of is the wiring harness for the injectors and the engine so we are looking into it. i will keep anyone updated who is interested

hello hope i can shed some light and maybe get some info..
i own a 99 ram 5.9l., i too just started getting the check engin light w error code p0300.
could it be from a bad catalyctic converter, i know mine has been gettin worse and it soundls like the motor is be muffled more now and the exhaust sounds like it breathing threw a straw. since the check engine turned on
i did my plugs and wires about 8 months ago ,
but not the coil or distributer
runs like ish over 2500 rpm
motor has 155k on it
any thoughts or suggegtions would be great ..thanks
