Ok where to start...... 84 trans-am- choke light stays on almost always and blinks rapidly sometimes, starts hard cold, when i swich from park to drive or anyother gear (automatic trans) the car moves forward alittle (bad explaining i know but its the best i could do) and when i step on the gas it hesitates, could this be all caused by my carb? wasnt havin any problems this bad before the choke light started to say on.

also when i step on the gas sometimes my rpms go way down then way up, and when i first start it, it idles really high 1100 rpms or so
