Issue 1:
The engine is running very rough. No power. I suspect it's running rich and fouled the plugs. I'll pull the back plugs later. Injector fuses look good.
Issue 2:
The RKE is intermittent. No idea. Suspect wiring. Sometimes lock works, but not unlock, or vise versa.
Issue 3:
The upper courtesy lights work, but not the lower courtesy lights.
Issue 4:
The adapter apparently makes the speedo whacko. When starting the engine in park, the speedo surges to 50, as if connected to test circuit.
Issue 5:
The oil pressure gauge can read correctly, but often points to the bottom right corner. Sometimes it jumps around
Issue 6:
The tach jumps all over, although it can be correct.
Issue 7:
The temp gauge can read correctly, but usually reads hot. Sometimes it jumps around.
I had verified gauge accuracy against the computer last year. It's hard for me to believe that all my gauges suddenly went bad.
Issue 8:
The transmission upshifts when you depress the accelerator, resulting in less power, rather than more. I also think it shifts a bit early.
