02 can put you in limp. Since you’ve been throwing parts non stop might as well keep going.
Ooowh
We we had one like this only yesterday , low power & O2 faults.
Now to be fair the owner had shot gunned it with a new expensive parts, (lots of them) plus an O2 sensor since it had rubbed through shorting out on the exhaust shield. AND as we know the O2 sensor control wire is on the same communication conduit as the MAF sensor. BUT the bloody thing still couldn't get out of its own way!
A really quick fix & solution to the problem was install a new air filter . (Well blow me down son)
Now at 78,583 miles I bet it was the original owner's modification -
-Don't change me I am K&N --Bollocks!
Doing a "filter frizby" to the trash can, we cleaned out many years of crap from the air filter & intake hopper installed a genuine MB paper filter and the van ran up I/70 like a revitalized stallion.
Why do people use this K& N crapola?
But then the answer!
In came an F 250 with that worthless 6 litre "head bolt blowing disaster " diesel in it and no power .
Turned out it too had a chocked K& N Banksy filter in it collapsed & choked up.
Now this guy wanted to argue with my female service writer who has a string of ASC's about the expediency of this crap.
After paying for the diag then came her comment.
