Well, we’re not exactly what you’d call a wealthy family, so we were very careful about replacing anything on the engine. We had to, at one point, cause the throttle was giving us grief, making the engine spin up to 5-6000 RPM with no reason. After we fixed that (some sensor was literally, physically broken off the engine, so that did that), we found out the gas pedal was acting up. Not revving up the engine, or doing it just sometimes. We discovered the capacitive resistor contact platelets (they run on a brass track and regulate the electrical signal used by the throttle). Got that fixed, and it was all smooth sailing on from there.
So you’re telling me the ECU tries to protect the engine from damage caused by low RPM by not letting it go onto higher ranges? That’s weird 😆
