Hesitation
I have a 1994 LT1 6 speed, several weeks ago I developed a stumble while accelerating, felt like trash in gas, changed gas filter and ran sea foam in a full tank. Problem continued, no codes, worse when accelerating from a dead stop and shifting gears, it is intermittent while accelerating and still pulls strong. Any help would be appreciated.

The strategy is to eliminate the easiest stuff first. Vt

can you drive around with it taped to the window to observe any fluxuations during the hesitation symptoms. just want to rule it out fully and move on.
also, does it do it right away from cold start in the morning or only after its been warmed up (helps guide toward open\closed loop)

It does it from start, hot, cold, all the time.

Perhaps so but when the demand is highest, can it deliver? If not, what other points can it not deliver? Delivery at idle is good but if it can maintain pressure all over, that is better.

How Long have you had this car? How many miles on the clock? Has the Opti been changed out, and if so by what Brand opti? When you had the plugs out did you run a compression check? Have you ever washed down the engine with water? Has the engine been overheated in the past? do you still have the old plugs, and did you keep them in order by cylinder removed?
