no i have a PGM-FI light indicating fuel injection problems. I checked the ecu, i was recomended to check the 02 sensors. Which os sensor is it, the one on the intake, cause that one is only a hose running into the top of the engine, not any chip or anything with wires, and my chilton has no pics. so the ecu says MAP malfunction, i've changed the plugs and stuff what elses should i check.
