If you used platinum plugs or e3 do em again but with copper lol. Otherwise download the factory service manual, it has the procedure in there. Easier than trying to explain it.

 

Um do you have a good source for me to download a manual ? Or should I go on a Google hunt ? Haha and thanks for all the help

 

What condition is your plenum gasket in? Multiple misfire codes are a tell tail sign.

 

hey so heres a little more info,

1-150psi
2-150psi
3-151psi
4-150psi
5-120psi
6-120psi
7-150psi
8-149psi

P0300 random misfire
P0302 cylinder 2 misfire
P0301cylinder 1 misfire

also threw a PO505 but cleared and never came back !

as for condition of the plenum gasket i am unsure at the moment

 

What wires did you get? If you just got the 'stock replacement' fellers, check the FAQ section here for the Plug Wire Routing TSB, and run them accordingly. Might be just that simple.

A high of 150, and low of 120.... puts you out of spec. Granted, the individual numbers are good, but, the difference between highest, and lowest, is greater than 10%, which isn't good. I would be tempted to do a cylinder leakdown test, and see what that tells ya.

 

A worn out distributor (Bushings) can cause this also.

 

As for the compression, run 2 cans of Mopar Combustion Cleaner through and retest it.

 

Wire Routing very Important!

So the update is I got my hands on a mt2500 and checked the sync. Its going in between -9 and -11.

Should be set to 0 correct ?

 

And cyl #2 is misfiring like crazy, turned injector 2 off and it ran way better, that mean injector 2 could be bad ?
