The P0087 Saga Continues

Good news! And good luck with the longer trips this summer!

Hi,

A one year report on big fifth wheel towing performance with the Kennedy modifications.

The almost 2,000 mile trip towing to Texas in ferocious heat last summer was followed by about 5-600 miles of other miscellaneous towing later in the summer. The code appeared once on a long, very hot pull coming back from Austin, I cleared it, and didn't have any more on that trip.

I just returned from about 1,900 miles towing down and back to the Gulf coast for our winter snowbirding. No 0087 problems at all.

I pronounce it money well spent.

Thanks for keeping us up to date. P0087 has been a problem for lots of folks.

Hi Rich,
I am considering just what you've done with my 09 lmm -(90,000miles- occasional change filter p0087 limp on grades in 100deg heat) and have a few questions. I know you left your dpf in place(as I most likely will) and there were some regeneration issues - was that solved in tuning by John or where is that at?I have already added a fass 165 pump and replaced the filter head and lines there - otherwise stock well maintained truck. Now thinking JKs tune/ecm to keep me out of limp and get another 100k before injectors. Also edge cts2 for watching regens and other temps. Anything I'm missing?

Thanks Rich,
Paul

Hi Paul,

I probably was over fixated on watching the regens at first. The Edge was a novelty at the time, and I watched every parameter closely, trying to learn more about what the engine was doing. Regens have absolutely been a non factor in the long run.

And aside from that one code last year, on a ferociusly hot day on a long hill pulling a 12+k# fiver, the original problem has simply gone away. Just hit 140k miles this week, and very happy I did it. John's a hero!

I do have some building questions about whether it's time for a new one. But that's another post...

I think you got it covered. Good luck.

Thanks for that info Rich. When your truck coded that one time on the hottest tow did it limp or let you carry on? Thats my whole worry is being stuck on the side of the road with no shoulder and family on board. Also if the dpf is working I'm pretty well good to order.
