In-depth look into p0300
I still have not opened up my engine, after flashing my pcm with a 800 rpm parameter 95% of my issues went away. At this point I would say it’s a sticking lifter in my situation. Its possible you could have the same issue, I would suggest doing a wet compression test on 6 to see if your...- MP9C

In-depth look into p0300
Well in further testing, last night I cracked the PCM turned off the MDS and bumped the idle to what seems to be a reasonable rate to me 750 rpm and I went from 1500 misfires on a drive down to 50 misfires on the same drive. So that is interesting, I am going to do a longer drive and see what...- MP9C

Well I didn’t get into much today but I did go pick up a mopar oil filter and tossed it on and it is still missing but I would say it improved slightly since the oil pressure went a little higher with the new filter. I still need to torque the intake manifold as suggested before and I am...- MP9C

I will have to look around and see if I have a manual gauge chilling anywhere. It’s not consuming any coolant I have not done the timing nor had it apart or know the history so…. There are some possible questions here.- MP9C

Well, You don’t have to pull the heads to change the MDS Solenoids. It doesn’t have an EGR valve. The crank position sensor has already been replaced. The compression numbers are posted and even the lowest one as well above Chrysler spec and within the 20% rule of the highest. If it had...- MP9C

Possible I suppose but with compression being as high as it is I’m not 100% that would cause the miss but anything is possible. An it seems to go away with a rpm increase so I really am thinking it’s something to do with the lifters collapsing at lower rpm an not opening the valves all the way.- MP9C

I agree but I’m going to go on a limb and say most guys don’t have a oscilloscope chilling in there garage. I was just pointing him in a couple directions of things to check to find out if his issue is load related or position related.- MP9C

Yeah Mister Luck, if it comes down to tearing it down I will be looking everything over, might even load all the springs to see the pressure rating on them to see if they all match up. An at that point lapping the valves at a minimum.- MP9C

Umm that’s definitely different, I can roll right into mine and it’s balls out it don’t miss a beat. For you I would check your fuel pressure and check your throttle body and pedal position sensor one of those could have a dead spot in the potentiometer.- MP9C
