Code p0303


P0303 is a misfire in cylider 3. This is almost always an ignition coil in this car. I would swap out all 8 with Motorcraft coils as well as spark plugs. If one is going, the others arent far behind and one bad one makes the others work harder.

Hi double check the code which came up, as P0303 is no.3 cylinder misfire.

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.
