My car- 91 integra gs. 98 jem B20B running obd0 electronics and harness. I bought it this way from a tow yard for 500$. At low throttle (10-30%) the engine hesitates and spudders almost as if timing is SERIOUSLY off. Lurches in and out of power band. No backfiring although it feels like there would be. Checked timing w/gun. Its perfect. Replaced ignition from the rotor to the plugs. Checked all electrical connections twice. Throwing code 13 (barometric pressure sensor) I can't seem to find a straight awnser on where this sensor is. Some say its located on the passenger kick panel. Others say its inside the Ecu. Both of those statements make no sense wouldn't it need tosend be integrated to the intake or at the very least under the hood? A huge thanks in advance to any suggestions. I bought this car so I could sell my truck and get me and my wife into a house as we are expecting in april. Thanks you guys.
