The last few times I've driven it, in the freezing cold conditions, I've noticed that the AFR has been starting to head northwards.
No codes at all, and being a simple narrow band engine it has to be something mechanical causing it, I've checked FPR lines and all sorts and it seems fine, and up to about 5.6-6k it's bang on, then goes wayward at the top end.
I can only imagine that in the ultra cold air it's making more power on the road than it did when mapped and the injectors have reached their absolute limit.
It was 29 degrees in the dyno cel when we mapped it, and inlet temps ranged from 24-28 degrees with the meth on, in last nights cold conditions inlet temps were below 0 with the IAT sensor flat lined at 0 it was so cold most of the time, occasionally creeping up to 4 and 5 degrees but never more, so it's a plausible theory.
That however, isn't the issue!
I went out to do some more checking on fuelling, focusing largely on teh AFR display, and suddenly I started to feel cold.
Hmmmmmmmmmmmmmmmmmmmm - most strange. turn heater up.
Still cold. WTF? heater was blowing stone cold. argh.
Looked at teh temp needle, and sure enough, it was creeping up beyond 90. Climate 49 confirmed this with a temp of 109 degrees.
feck.
Just a mile from home I decided to try and gently limp it home, but as the temp reached 119 I bailled out of that idea and pulled over killing the engine.
I popped the bonnet, and used the last 3% of my phones battery power to light up the bay looking for issues.
EVERYTHING LOOKED SOAKING WET!
feck. again.
phone battery died. feck all I could do, so waited for it to cool then limped it the final half a mile home and got my torch out.
It wasn't wet at all, that shiney crap was infact Jardo's cleaning products from the weekend! haha.
You'll never believe where the ****** water had escaped though....
