Anyone seen this before:
It only happens at 2400 rpm & above.
New Knock sensor.
new distributor.
spider conversion
new plugs
all four o2 sensors new
new cats
new single chamber mufflers
I'm at a loss. the truck gets 18 mpg running around 2200 rpm or less. Drops to 14.0 at 75 (2400rpm) and gets worse from there.
