So this may be a stupid question be I just got my Jimmy back with the new 4.3l. Im not ****ing up and missing warning signs a second time. Heres what Im noticing
Revving to 3-4k through the gears without trying
Hard shifting
Lack of Power
Power band all off
Little rough on the idle
So what could all of this mean? Is it a transmission issue or possible fuel/intake/exhaust? I did get a new catalytic converter before I got the new engine.
The new engine was a 4.3l out of an 01 Oldsmobile Bravada if that changes anything.
