08 xp.
I believe I got some bad gas today. runing a turbo at 7psi. sled just seemed lazy on top end and did not pull through really well. Only pulling 8,000 rpms. check engine light kept flashing. checked plugs and no signs of detonation.
I get non ethanol pump 91 from this same gas station every time I ride. I had 2.5gal in my extra can that I filled the week before. Dumped it in and it ran way better and was hitting the rev limiter now. still kept setting off the check engine light though. it will not shut off. got home and started it and it still comes on. It beeps 4 times. Is this any kind of code like on the cats or do I have to take it to the dealer to find out what the code is?
I thought I had heard something that if it was a soft knock it would flash, but reset when turned off. If it was a hard knock it has to be taken to the dealer to be reset.
I know I have heard that the first couple 09 xps had to be taken to the dealer to be pluged in to reset the knock sensor, but could be updated in the ecu program so it will reset when you turn the sled off.
