Unless that guy is hauling in the southwest, my guess is he will have more issues next summer when higher temps return. Ambient temps which contribute to high fuel temps are a big part of this issue.
I am finishing up a 3000 mile trip today, with a heavy wide boat and through terrain that would have tripped the P00087 many times last summer. So far only two codes set, and that was running hard uphill with a low tank of fuel. The only difference? About 30-40 degrees less ambient fall temps.
This issue is best solved via programming tweaks, but it is clearly a combination of all that has been discussed, including:
If I'm still hauling boats next summer I will buy your finished product, if it can be warranted to solve yproblem. However, my goal is to be in Seattle driving a 2012 ZL1 Camaro by then, although I may be driving my daughters Jetta if I can't find anyone to buy my biz...we'll see which happens first!
- High mile or high fuel volume injectors (i.e. always towing)
- Heavy loaded towing, usually compounded by hills
- High fuel temps, caused by excessive return rates, low fuel level in tank, poor fuel cooling or flow, etc.
