Knocking or missfire
Hi all
Hope I will get some answers to this delima.
It started as a cam POS sensor, replaced it no problem,then I got a vacuum leak,so I replaced the intake manifold gaskets.
Put it all back together and now I have a hell of a mess.
Rough idle, backfire, missfire down in the exhaust pipe.
New plugs,wires,coilpack is checking out ok.I tore this down several times now and no go.
Any help will be greatly appreciated
2002 ranger 3.0. 142000 miles but it was a strong motor till now
