my jeep has a miss at idle. it does it once the jeep has warmed up to operating temp. these are the faults it's throwing. can someone please shed some more light on the following codes? do they mean that i need to replace all of the sensors/soleniods etc?
P0100 mass or volume airflow circuit >
maff sensor signal voltage to high or too low.
P0190 fuel rail pressure sensor > fuel pressure sensor signal voltage too high or too low.
P0299 boost pressure control deviation > boost pressure sensor positive deviation.
P2294 Fuel pressure control valve 2 > fuel pressure solenoid open circut

i just replaced the fuel rail (have a spare kj for parts) and it seems to have fixed the miss. 
one of the lifters is ticking at idle.

I would go to the p2294 first, since it's the only one that's a definite what and where.

With yours being an export and being unsure of the year model,

I can only point to Sir Sam's site for my particular year FSM.

Page 3990 is where the P2294-FUEL PRESSURE SOLENOID OPEN CIRCUIT trouble shooting procedure starts for mine.

It may be as little as a loose connector.

[edit] Woops, should have re-checked when I got back to the keyboard. :juggle:
