imperatif

I have a 2004 Sportster. I have been complaining about long beep (random) for 2 years now. I had dealer put computer on it 3 times so far and am getting very confusing computer read outs. Fuel sensor out of range 255 times in 2 years...; MAG TPS adaptation failure 40 times in 1 year; PTO TPS adaptation failure 39 times in 1 year ; those messages were confusing to local mechanic so we cleared settings to 0 last week and will wait for next failure and then rush boat to dealer.

BUT IN THE MEAN TIME, i LOOKED AT MY SPARK PLUGS AN ALMOST FELL ON MY BACK WHEN I SAW HOW CARBONISED THEY WERE. DARK BALCK AFTER ONLY 100 HOURS OF OPERATIONS. I DO A LOT OF LOW SPEED BOATING AND MAYBE THAT WHAT ENOUGH TO CARBONIZE PLUGS AND THEN TPS SENSORS WOULD SEND DISTRESS SIGNALS....

i CHANGED BOTH PLUGS LAST MONDAY AND AM SURPRISED TO ADMIT THAT IT RUNS LIKE A NEW BOAT. IT IS STRANGE, BUT 2 NEW PLUGS TOOK CARE OF A 2 YEAR OLD PROBLEM. SENSORS WOULD COST 200$ EACH. THE PROBLEM WOULD OCCUR EVERY SECOND DAY BEFORE. PLEASE LET ME KNOW ABOUT THE PROGRESS OF YOUR FINDINGS.
