Re: Knocking or pinging under accelaration with lower grade fuel
Well it finally threw an engine code, (401) insufficent EGR flow or something like that.
Changed out the Vaccum sensor (DEFP whatever it is called), small Aluminum casting with 2 hoses and the multiplug connection, seems a little better, pings ever so slightly,
now I have an Exhaust Manifold problem. either the manifold gasket is shot, the Manifold has a crack, or a hole, or the Dougnut between the manifold and downpipe is shot.
F***ing typical, change one component and something else goes bad.
only had the truck for 8 months now has 91,000 miles on it.
I Will never buy another American Ford, I should have learn't my lesson with the UK vehicles, such as the two Escort XR3I's, Sierra Sapphire and Escort RS Turbo I had.
Dealer quoted me $408 for Exhaust manifold, being as Discount Auto doesn't have that part of the system, typical.
will have to remove the manifold on Friday, this week, to see if there are any cracks etc. already got a new gasket and Doughnut ready, anyone have any hints or tips on removal of Manifold, knowing how bad the nuts seize up.
Also does anyone know what the torque settings are for the manifold nuts and the downpipe bolts being as the crappy Haynes manual doesn't have them listed, don't want to bust any bolts. etc
