KAM is keep alive memory. check your battery and see if it is holing enough voltage to keep the memory. If not odds are your pcm is on the way out.

SOURCE: rough running, erratic spark
Run a compression test on the cylinders.If reading is low on any drop a little engine oil into the pot. If compression rises you have compession ring problems. Remove all plugs before you try this and place leads away from engine.

Have you checked for spark on all 8 plugs? Unplug the exhaust side coil pack and run the engine. Does it run on all 4 cylinders?

SOURCE: check engine code of PO430.
P0430 - Catalyst System Efficiency Below Threshold (Bank 2)
What does that mean?
Basically this means that the oxygen sensor downstream of the catalytic converter on bank2 is detecting that the converter is not working as efficiently as it should be (according to specs). It is part of the vehicle emissions system.
FB.init("dd7d9e9681341cde77587bc6a2029f6f"); OBD-Codes.com on Facebook You will likely not notice any drivability problems, although there may be symptoms such as a rough/hard idle when cold.
A code P0430 may mean that one or more of the following has happened:
Possible Solutions:First, inspect for exhaust leaks.
Next step is to measure the voltage at the oxygen sensor on Bank 2. In fact, it would be a good idea to test each oxygen O2 sensor while you're at it.
One thing to note is that many vehicle manufacturers offer a longer warranty on emissions-related parts. So if you have a newer car but it's out of it's bumper-to-bumper warranty, there still may be warranty on this type of problem. Many manufacturers give a five year, unlimited mileage warranty on these items. It's worth checking into.

Hello, you might try a new fuel rail pressure sensor. This Code 0088 is for high pressure at the fuelrail. It would be possible to rig a testing pressure gauge to the truck and drive it to see what the pressure really is. If the dealer has a Dyno, he could run it in the shop.
Some of the reports I am reading is the Turbo boost for other owners is starting to max out about 70-75 MPH with a load and usually going up a grade before this light comes on. A certified Pressure gauge would show whether the sensor is tripping too early.
I want to believe there are some specs the Dealer could use to bench test this sensor. But if the end result is buying a sensor and paying Labor you could just go Aftermarket and install a New sensor yourself.
Would like to know the final solution on this.
