Bringing my baby to the shop

[Lin]

Earlier this week, after a 50 mile ride, the "Check Engine" light came on. I checked the codes and found: P0171 ECM System too lean Bank 1 & P0174 ECM System too lean Bank 2. I drove it the 50 miles back home and didn't notice any anomalies with performance, temp, etc. After reading several past threads, I plan on driving it about 50 miles to the dealer this coming Saturday. Does anyone have any advise against this?
Thanks in advance

This next trip to the shop will be the 4th time its been in for the same issue. So far they can't solve the problem. Let me know if you get a fix for those codes and I'll do the same for you if I get a fix. I started logging all my limp modes by millage so I'll have a record just in case worse comes to worse. Oh, by the way, mine seem to run fine. I've had no problems driving it to the dealer.

Should be no problem driving to dealer. Please keep us informed about the fix.

Ride it . I had similar situation for months where they couldn't find a real problem. Too long a story, it is apparently fixed now with new left fuel injection sys and 2 new plugs. I just kept riding it because it ran perfectly. Very frustrating though. Throttle potentiometer was replaced twice, I put 1500 miles on a loaner 2014 limited during two extended shop visits where they checked everything, but P0174 just kept coming and disappearing or they reset it with the BUDS computer. And that obnoxious orange screen flashing and going nuts was a pain. But it's been a really great bike and think it will be until I quit riding in my "ever older"" old age.

sounds like your o2 sensor may be giving you problems. Then again if you clear the computer with the key walk the ryde again with out getting the problem it could be a lapse in the system. Happens. As far as ryding to the dealer you should be fine on a liesure ryde...

this afternoon and evening and had 7 limp mode stops to reboot (I guess) the computer by turning off the bike and removing the key. 3 instances were in daylight and 5 were in the dark. Wife was not happy about sitting in the dark along a lonely section of freeway and back roads waiting to clear a limp mode. I wasn't happy with a flashing orange screen in my face, in the dark. But,,,,,,,,,the bike ran great. 42 MPG 2up in the mountains. Can't get much better than that can you? The folks we were riding with were getting a bit unhappy so I told them to stop waiting for me and go on home. I'd call them later to let them know we got home alright. If not, please feed the dogs until we show up.

We also have had a recurrent PO174 code/Orange Screen on our 2011 RT SM5 on about 4 different occasions. Last time in was last November and had a new oxygen sensor and previous times had had throttle bodies, canister replaced and purge valves replaced at different times. It appears to run fine otherwise, and I have always checked the temps and other vital fluids and driven it for short trips until we got it in for an appointment.

Today it showed up again and we finished our 100 mile group ride with no issues other than the alternating orange check engine light/screen.

Hope someone finds a fix. All service time has been documented and on warranty. 66,000 miles and counting.

I just picked her up this afternoon. It had flashed the check engine light all the way to the dealer last Saturday. The tech found several codes that suggested purge valve or fuel pump. Both tested fine. The codes were cleared and have not returned. Keeping my fingers crossed they don't.

Check your Spyder's throttle body vacuum lines.
The two small vacum lines connected to the throttle bodies are notorious for getting brittle and cracking due to the temps under the plastic.
They can create many lean conditions when they leak air.

Unfortunately, the OEM replacements are made of the same material and will fail too.
Many people go to there local auto parts store and buy high temperature silicon lines, cut them to length to match the original lines, and never have anymore problems.

Thanks Mike. I knew about the vac lines and specifically asked if they had been inspected. They had. I have been on a couple of rides since getting back from the dealer and have NOT had the problems recur.

Good luck. I have a 2103 RT-S and I have been contemplating replacement of the hose with high temp silicone lines so I don't have to worry about them.
