i dont know if this is FI related but since my car is turbocharged ill post my question here. to start off, my set up is a 96gsr motor w/ DSM 450cc injectors, walbro 250lph fuel pump, hondata s200b with a t3 boosting 7lbs tuned by DynoSpot racing. latley my car has been hesitating alot when its cold under 3k RPM. if i tap on the gas the rpms will drop and the engine will almost stall. it seems to go away once the car is warmed up, but even when its warm, if i try to hold my car at 1.5 - 2k RPM in neutral, the rpms will slowly drop untill it is about to stall then suddely jump back to 2K or whatever rpm i was originally holding it at. in gear, if i try to cruise at about 2K rpm, the car will jerk a little bit. the car also occasioanly throws a CEL 43 (fuel supply system) when its cold. i've replaced my o2 sensor, cleaned my injectors, changed my spark plugs and wires. oh yea and the fast idle valve and IACV are bypassed incase that might do anything. i havent done anything to the car or changed anything so this kind of happened out of nowhere and slowly got worse. i've run out of ideas, does anyone have any suggestions?
sorry for the long post.

what does your cap and rotor look like? mine did that...i didnt know what it was but my coil went bad and i put in a new cap and rotor cuz they were pretty worn and voila no more hesitations... but im still NA tho worth checkin out

i actually replaced my cap and used my old rotor because the store was out of stock, then i replaced the rotor a few weeks later. this was about a month ago, do you think it could still be a problem? that probably wasnt a good idea, but its too late now. ill check though, thanks.
