Fuel Pump Issue?
So I've done a lot of searching and just want to make sure I've covered all my bases.
Issue:
Engine won't rev past 7k, huge puff of white smoke (oil) is produced and power loss occurs momentarily. Causing CEL codes: Cylinder 2 misfire(P0302) and Rich Air/fuel ratio bank 1(P0172)
Variables:
80k miles currently
Spark Plugs last replaced at 50k
Cat replaced at 40k
Fuel Tank was at less than half
Hypothesis:
Fuel pump is going bad and can't provide enough fuel for the upper ranges of the rev band.
Action Plan:
Replace OEM fuel pump with Walbro from BHR
Replace spark plugs with NGK plugs also from BHR
So does this cover all the bases to start addressing the issue? I know coils are possibly the cause but I'm not ready to sink $500 into the BHR set.
Thanks for reading!!
