Well, you'll have to remove the fuel rail and look at the inlet of each injector. When doing that, It's advisable that you replace the upper O-Rings, unless you pull the injectors. When replacing O-Rings, lubricate them with a light oil so they don't tear. Gunk tends to accumulate on the passenger bank of the rail toward Cyls #6 and #8. If the injectors are clogged, they can be cleaned by using a jewelery sonic cleaner that can be purchased at Wal Mart for ~$90. It's cheaper than shelling out $$ for new injectors and they'll be like new. Use mineral spirits as a medium in the basket.

 

How long should I keep the injectors in that machine? Once done do I clean the mineral spirits off or just pop them back in the fuel rail and keep on going? Also if there is rust or trash in the fuel rail how do I clean it out or do I replace the fuel rail? I know I have a lot of questions but I am really frustrated with this truck to the point I'm about to sell it.

 

You should just seafoam or techron+ it to death first. Your getting random multiple misfires so they would all have to be clogged. Maybe you just got some bad gas. In your gas tank that is.

 

Do you have access to a parts washer? You'll have to soak the rail to be able to get any clingy crud out of the insides. Also, DO NOT attempt to disassemble the rail. It looks like it can come apart, but the Dodge manuals *specifically* state not to attempt it.

Also, the cleaner cycle is for a few minutes. Just keep at it until they're clean and then let them drip dry.

 

Well that has been known to happen.......both ways LOL! O'Reilly's has this 3M fuel injector cleaner kit with everything needed for about $50 bucks. Also there's this pick up coil that sits below the rotor in the dist. I was told when those start to go they can cause multiple/random misfires also if the dist shaft wiggles.

 

That could be, and THEY ARE not very expensive.LOL Worth a try I guess. However, I know the Techron works. Long ago when my original cat went, after I replaced it I still had random multi misfires. I just kept putting the Techron in it, and few weeks later the misfires completely went away without doing anything else.

 

That would be the CKP sensor. Pull the cap and ensure it's tight. You are correct -- they are a cheap part that can cause the misfire. This kind of crap will drive you nuts, but then again, by following everything we recommended, you're performing a lot of preventive maintenance.

Where?

 

Rock Auto for one. But I just called my parts store and it's like $42 because I have an account. SMP brand.

 

YEAH OREILLY'S HAS IT FOR $45 AND YOU'RE RIGHT AS FAR AS THE P.M.ing GOES. So I'm going to replace the coil, cat, and that sensor. I'm going to "SONIC WASH" the injectors and soak fuel rail in parts washer correct? after all of this and that da%#m thing still screws up there will be a new truck on my posts from now on.

 

Take it a step at a time. Check the cat first and if it has to be replaced, thus fixing the problem, I would draw up a gameplan for the rest of what we discussed. If it isn't the cat, then start looking into the other repairs.
