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.

Engine misfiring.


most all v8's have the same firing order which is 1,8,4,3,6,5,7,2. sparkplug gap seems fine. with the engine off, bend the sparkplug wires between your fingers, if small cracks appear then replace them. number one sparkplug is located at the front driver side of the engine, front to back on this side are cylinders 2,4,6, and 8 respectively. turn the engine to the compression stroke on number one, pull the cap, the rotor points where number one will be.

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.
