This has a whats called spider injector .if it goes bad like say leak into the intake it will cause these misfires if you have a scanner look at the o2 voltage output on bank 1 if it reads .350 or less and the other side is reading up and down from .250to .850 than suspect a bad spider injecter.

1999 Chevrolet Suburban cylinder 3 misfiring?


P0300 is a multiple cylinder misfire and is used by all OBD2 vehicles on the road in the USA that is 1996 and newer, P0301 is cylinder number 1..P0302 is # 2 and so on...that tune up may have been needed and parts and labor are expensive..you have a cylinder that is misfiring and the cause must be located..possible causes are intake manifold air leaks..secondary ignition problems..fuel injectors..plugged EGR system if it has one..failed head gasket..burned or cracked valves..I have seen some crazy stuff..you need a tech on that one not a mechanic.

Most probably and if a cat is not flowing proper is causes back preasure that can result in sticking or burned vavles,mechanic not nice by saying ignore the cat effiency code p0420.Can ussually have cat replaced at aftermarket muffler shop for approx. $200 cheaper than valve job or excessive fuel that you have used and damage that may occur to your engine.

When trying to cranking engine the fan rotates forward then rotates backwards would this be caused by the timing chain? 1999 chevy suburban


You don't say how many miles the engine has. The engine is misfiring and running backwards momentarily. In days of old this was from the timing being too far advanced. With the new computer controls this is more difficult to achieve. Are the plug wires crossed up? I have a1999 Silverado 6.0L and it has a coil for each plug and little short plug wires. The wires to the coils just out of the loom near the front of the engine may be of similar length and could get crossed up. Have you been messing with things? Or is this something that just started happening? If the timing chain is so loose it jumped teeth then maybe. As it gets looser the timing would ****** some. Does this happen when the engine is hot? Bad plugs with hot deposits on them can act like a glow plug and cause a premature misfire when cranking. Very hot engine shut off then restarted right away.
