well guy at work got a 99 silveradp with a 4.3
miss when diving the miss shakes the vehicle... code say multi cylinder miss fire, cad bank one low , then latter the multi miss went away, read only cyl 2 miss fire .. then back
done cap, rotor, coil, coil mod., plug, wires, over the week en and didnt help...
any idears ??? i thought it was out time on the dist.. but this is to new for me???
the gear on the bottom of dist. ? intake leakin
I had the same code on my 2002 chevy 5.3 made my cel flash I replaced cOils plugs and wires and it was still there i asked around and I found out it was the cats bc they were plugging up sO I cut them off and haven't had the code come back yet. It also made my truck shift really weird when I would go balls out. It would get to 4500 rpms and hold right there till I let off.
cleaned cats out already the last time this happen bout 6 mon ago...
ther is a box on the top of the intake, where fuel lines go and a big plug in with a 16 terminal set up.... anyone know what this is ...
lol with out seeing it...
just found out that that box was full of water, from the rain other day, because there is a piece of weather stip missing above it
