Ok. Well ill check fuel pressure and change the fuel filter first. I can imagine that is cheaper than the PCM. I have had the vehicle for 2 years now and haven't changed the fuel filter and I highly doubt the people that had it before me did either. Ill throw some Sea Foam in the tank afterwards as well. If that doesn't solve the issue and I get a new PCM will I have to get it flashed like an ECM?

Changing the fuel filter is not as easy as it seems for the V6. You might have problem accessing it and according to the manual, the tank has to be drained and partially dropped.

That's ok. I've got a car lift and a transmission Jack. I noticed that it sputters and misfires A LOT more when I have overdrive off. I usually drive with it on.

With OD off, the engine would be runnig at a higher rpm and with more engine torque, the misfiring shoud be felt less.

It runs around 3500 RPM with OD off on the highway and it does misfire and sputter a lot more. Then when I turn overdrive on and the RPMs drop it stops. Sputtering and misfiring as much.

Get the fuel filter replaced and see if it makes any changes.

I changed the fuel filter. It was bolted to the frame so I did not need to drop the tank. But it is still misfiring : /

Are the trouble codes still showing the same codes or are there any additional codes?
