My BP150 engine is running lean I believe and is generating extreme exhaust temperatures.
Just an FYI the entire water system has been replaced and internal water passengers cleaned as well.
However, assume that cooling is not the issue.
Since the engine is controlled by the ECM based on multiple sensors. I'm looking for the one that alters fuel/air. Likely the 02 sensor in concert with MAP and BAROMETRIC.
If the engine is running Lean and further Leaning with VTEC engaged, what sensor fake out to so the ECM will increase fuel into cylinders and thus cool down combustion?
My guess the excessive heat is due to the engine running too Lean, so like to change fuel injection somehow to maybe get it to run a wee cooler.
Note: Engine idles, runs, accelerates just fine until the Exhaust Temp Alarm is sounded and I have Engine shutdown.
