l 95 Trans Am l

Cars running flawless, and this isnt a big issue, but ive noticed that my car seems to hesitate when im just sitting around 1000-1500 RPM and i just stomp it, it has about a second lag then it just throws me back and spins through first. So im really happy its just that lagtime has me a bit worried. New parts are Opti (GM), new plugs, new ICM, TPS sensor, Walbro fuel pump, new FPR, and new fuel filter. Only parts not replaced are coil and the plug wires. Could either of those cause a "lag"?

Alot of lt1's seem to have hesatation, does it do it while in open loop (for the first couple miles you drive it) if so you might could get a tune or could be your 02's do you have bosch by any chance? also any codes?

walbro pump on the stock wiring harness?? might be loosing fuel pressure when you step on the gas
