yo
i have a 88 HF CRX with a b16 swap, hasport harness PR3 Ecu, unchipped or programmed. Its been running wierd for the last month or so, in any gear at constant throttle for more than 2-3 seconds the constant power falls out and tends to bog untill i hit the gas again. This problem happens once the car is warmed up all the way. I havent been getting any engine codes, i replaced, the fuel filter, injectors, plugs(gapped properly), wires, timed it properly, and problem still occurs. yesterday while driving after an hours worth the CEL comes on, so i checked the Ecu and it was flashing code 2. Well, there isnt a code 2 in the acura GSR manual or 88-91 CRX manual,,, WTF! anyone know what the deal is? Could it be a messed up ECU? TPS? My plugs are running fairly white, so its going lean, obviously a fuel problem. any suggestions? The previous owner tied the two 02 sensor wires into the one o2 sensor, is that the problem? thanks to all that help me out!

Code 2 = 2nd O2 sensor, and since you're running a stock PR3 ECU, it looks for both O2 sensors (found on the primaries of the stock B16A exhaust manifold). Check the connections to both O2 sensors, and change the 2nd O2 if needed.
