Title: Engine miss
Post by: 76k104x4 on July 10, 2011, 05:58:37 pm

well first off i have a 76 k10 with 350 manual 205 transfer case factory Qjet when im driving and i give it the gas i hear it missing it gets worse the more gas you give it it still has power but i mean you can really hear it missing it idles like a champ but if you rev it up real hard it will miss while idling i tried changing my spark plugs air filter and fuel filter i dont think its my wires because it idles great and idles fine up to about 2000 RPMs just wondering what you guys think it could be thanks

Have you checked for a exhaust leak. it can sound like a miss or tap

or an exhaust clog, creating back pressure.  Or, check rotor/cap/wires?  it can idle fine and still cause problems w/ higher rpms if rotor/cap/wires need replacing. Gotta replace frequently anyway, may as well do it, if nothing else to rule it out.
