Hmm, did you see their spot out on the Island? Right now there are 2 in the parking lot. Seems unlikely they would take their spot off the bike.

Great report for a great ride.  I'm always impressed because I've been down most of these roads but it's taken me many trips over many years to do it.  

so in the end my problem was low fuel pressure, like only 20 psi.  This was caused by a problem I caused when I pulled apart my fuel pump to repair a broken off the barbed connection where the hose attaches to the pump.  And that happened when my tank took a tumble off the bike because I had it...

Well I'm pretty embarrassed. But let's just call it a series of unfortunate events. Albeit mostly self inflicted. But it's all fixed and running like it's supposed to. And note that I've edited the first post in this thread so a guy doesn't have to read the whole thing to find out the answer to...

Anyway,  thanks a ton to everyone for listening to my ordeal and providing comments and suggestions.  You assistance in the this endeavor is greatly appreciated.

Very good informative thread.  Concerning fuel pressure.  I say don't sweat the 47.0 psi specification.  Even 20 might be enough to get you home. My problem seems to be a bad fuel pump or fuel pressure valve.  A couple months ago after I replaced the coolant hoses going to the low idle wax valve...

well I finally got a pressure gauge installed and it only makes about 18 psi and immediately falls off to 0 when the pump turns off.  I think the pump may be fine but the pressure control valve is ka putt.  I'm not completely sure if the pressure relief valve is also a check valve and should...

hey 1911.  thanks for the info.  Why does unplugging the O2 sensor rule that out? Yes, checking fuel pressure is next but I need to gather up some materials and make a hose kit.  And, how do you test voltage on those little wires. I've used posi tap wire tapes for permanent taps but I don't...

I've always thought that most ECMs run open mode until the engine warms up and them closed loop. I'd like to know at what temp it goes to closed loop.  Last night I think it was up to 140 but it runs so rough and is missing and backfiring so much I'm afraid it's going to wreck the timing chain.

Last night I started it with a good deal of assistance from the starter fluid. Unplugged the O2 sensor and got no error and no change if rough idle.  Then unplugged the air box temp sensor and it lit up the warning light but no change in rough idle. Plugged that back in, error light went out and...

Close but no cigar.  A year ago (July 29, 2020 to be exact) I was in Ashville with my 3 brothers. We were working on getting the rear tire replaced on my younger brothers 2007 FJR.  Yes, it's a little weird but 2-1/2 years ago we both bought 2007 FJRs within a week of each other without knowing...

so did a repair of the TPS wire fix your problem?

thanks.  I was doing diagnostic mode and had started it a couple times but did not run it very long just before doing the video.  Actually this video was the 2nd attempt but was no better than the first one - LOL.   Anyway, the battery was run down a little but I'll give it a charge and check it...

To help you avoid reading this entire tread just to find out in the end that this is very unlikely the answer to a similar problem you are having.  In the end the problem was because of a mistake I made when reassembling my fuel pump way back about 2 years before the "running crappy" cold start...

I'm gradually learning a bit at a time how this system works. According to the Supplementary Service Manual pg. 24, the engine will continue to run in open loop mode if a sensor input is out of range, well for some sensors.  If the lean angle sensor is goes out of range the engine shuts off. ...

how about O2 sensor?  It does not show up on the "diag" list.  I assume it provides info for the control module at least when running closed loop. I assume a FJR runs open loop until it warms up???  Anyone know this??   Maybe I'll unplug it and see it it throws a code.  The only other bit of...

Thanks for the additional comments.  It's not been sitting in the sun much for the most recent occurrence of the problem and it's does not have any CA emissions stuff that I can tell, at least there are no extra hoses on the bottom of the gas tank other than the overflow.  And I finally found...

the saga continues I had no problems on my trip to South Dakota.  8 days, 3600 miles, most of it in ID, MT, SD, and WY.  It started and ran perfectly every day.  The morning after I got home it would not start without pumping the throttle and runs horribly. I checked the diag codes again and...
