lt1 choppy-idle and choppy-accelerate I've got a 94 z28 a4 with slp intake and exaust, normally it runs very well but I parked it for 2 months in my brothers shop and when i started driving it again it had a choppy idle and acceleration. I've since replaced the plugs, wires,m.a.f. sensor, o2 sensor, air filter, fuel filter, ran fuel treatment,octane booster, and its got a newer opti-spark on it, not sure what else to check, any suggestion would be appreciated, thanks.

check your battery voltage before the opti. my car runs like crap when the battery voltage is low. i would say moisture getting in the opti is slim, but then again i am not sure of you location.

my car was doing the same thing last winter it was idling rough, jerking a little bit going down the road with no load, missing a little when lugging it, i changed everything you did except for the distributor since its a newer dynaspark and finally i figured out it was a flaky coil wire and a corroded coil terminal, usually people neglect the coil wire when doing wire changes so definitely give it a try
