Not really new topic

Post by GaryNC »

Think I know the answer but here it goes. 2003 Honda GW GL1800. The famous 26 code. Started last year then cleared up with ethanol free gas the only thing changing. Started back about a month ago. Bike has been fine, until today. Ride about 100 miles and get back home. Starts idling rough and cuts out. Start again and continues almost like choking off.

I am the third owner with less than 30,000 miles on it. The bike will fly down the road. Earlier in the year did a 200 mile trip with no codes or problems. On that trip I did have to put the nasty gas in to get home. But has been ethanol free since.

Any suggestions.

The fuel probably has nothing to do with it, the early 1800 ECU's are famous for throwing false knock sensor codes. Your ECU may have an intermittent connection inside, but these ECU boxes are potted in epoxy internally and are NOT serviceable. :cry:

Could be in fact a bad sensor (this is rare), but you can test this by swapping the sensors from left to right sides. If the code changes from 26 to 25 you have a bad sensor. If the code stays 26 then suspect the ECU.
There are 10 types of people in the world, those that understand binary numbers, and those that don't. :lol:
