I have a 91 4WS with a B20A5 swapped into it (the guy before me did it and didn't do it right). He kept the B21A1 ECU, throttle body, intake manifold, and more. I believe I have a throttle position sensor issue due to the 7 LED blinks on the ECU (tried putting in another TB from a salvage yard and still the code 7) and now I noticed (which could have been there before and not noticed it) it is displaying a second code with 1 long blink and 7 short blinks. Would that be a code 17 rather than it displaying 17 short blinks? Code 17 is the vehicle speed sensor, if it is a code 17, what symptoms would that typically cause? Currently the problem I am having is I am losing most of my throttle power above 2000 RPM where it just bogs down when I hit the gas. This is really only an issue after about 15 mins of running. I appreciate all the help!
