Hey everyone!! Ive been having problems with my 1998 dodge ram slt laramie 360. It has lost power. I went to auto zone today and they told me i had a misfire on cylinder #4. I just replaced the plugs last week so im thiunking the spark plug is either cracked or bad, or the wire is bad. What is the cylinder arrangement for a 360. Where is cyl #4. The wires numbers are different then the actual cylinder??

Thanks

i appreciate everyone's comments. Thanks, it helped alot. Ill be fixing the problem tommorow now that i know where it is at. I really need to get a service manual. What do yall reccomend??

Thanks again!!

 

educate me... how does the pcm know there is a misfire on cyl # 4 ?

 

i've been wondinering how the PCM knows where the misfire is also...i'm guessing it's one of two things. one is that it just looks for spikes in rpm from the crank/cam position sensors, and knowing where the crank is in it's cycle determines which cyl the misfire is in; the other is monitoring ignition coil primary spikes. there are scope setups you can use on ignition systems to determine misfires; you can see all kinds of things from ignition spikes. it's possible the computer monitors primary coil voltages (coil is just a transformer, what's on the secondary is on the primary) or currents and watches for spike patterns that would indicate a misfire, and again knowing where the crank is in it's cycle, detects a misfire. anyone know for sure?

 

They pulled thecode out with the actron scanner. Those things are awesome and i think we all need to get one. You just plug it underneath the dash and in 10 seconds it told me that it was cylinder number 4 misfire. Yeah, off topic sort of but really how does the pcm know??

 

My pcm was seeing a random misfire and after messing with the distributor position I fixed the problem.Guess it put the cam sensor in sync with crank sensor. Gained alot of power also!
