Thank you for the info on the fireing order on my 99 subruban. the check engine light came on and when I checked it it gave me a code of #6 cylinder missfire,
I cleard code and it ran for 20 or 30 mls, and it came on again, so I'm checking the wires and spark plug,
if that dosent do, ware do I go from there?
I am not working so I can only send $5.00 I Hope that will do, for now

Thanks in advance
Warren

Next would be to inspect vacuum hoses for damaged or loose connections. Check throttle body and intake manifold for vacuum leaks. Also the PCV valve operation and vacuum lines. A compression check and leak down test on the cylinder will be needed if you still haven't found a fault.
