Finally got my problem solved with the stumble on acceleration it was after changing fuel injectors mass air flow sensor IAC TPS oil change fuel filter seafoam and probably a few other things I forgot that I changed and then I finally took my jerry chip ECU piggyback out and put in my Superchips that had a custom tune and I finally had the upgrades to match the tune and it completely cleared everything up I'm thinking the engine was getting too much air at first and that the computer had to adjust and once adjusted it ran fine but that's exactly what it felt like ,like it was getting way too much air. but I would double check on the tune. Maybe it needs less timing until it's warmed up
