i had a similar problem when using the check valves...

 

i have the missing link, ill throw a code 72 every once in a while

 

Have you checked out your FMU.......

(happened to flamenco-t)

 

72 cylinder 2 misfires, it happened to me, all four cylinders misfires, it turned out that I have a defective FMU, the FMU stays wide open at idle and vaccum, so practically dumping all fuel to the cylinders from teh pump.
replaced my fmu last night and no more bogging or CEl...

might want to check your FMU...

 

yeap, same thing happened to us too, too much fuel. Turned it down and it did wonders
