Po304

[350VortecSSCT]

threw the engine code betwen 70-100mph...i take my foot off the gas and put it back on and it sounds like its choking or the spark is not being fed.

Im having the same prob with my Tahoe Limited, but im getting a P0303 Code. What i do know is...the 030* codes the last number is the cylinder number & it is misfiring. I've read it could be spark plugs, spark plgs wires, dist & rotor. Some say improper gap on that cylinder spark plug. I havent found out whats causing mine yet but when i do i will let you know.Oh & im also getting a P1345 code with mine are you?

Both of you need to have an injector bleed down test performed as well as have your fuel pressure and fuel volume checked.
