Hi
Thanks again for all your continued help. I took the truck for its test today.
Good news is it's mostly OK (including all the things I've fixed!). It did fail on emissions - high CO (7.3% vs limit of 3.5% at idle) and HC (1755 ppm vs limit of 1200 ppm at idle). I've been reading threads and will crawl over the engine later.
It drove fine on the way to the tester. However, on the way back, the revs insist on sitting at 3000, and only come down when you engage the clutch (so it's under load).
I expect it's a sticky cable, although it's not immediately apparent. My question is, could this be speed sensor related? I ask as someone had deliberately disconnected it - for this reason? I recently replaced the senor because I want and need a working speedo.
If, however, a duff sensor doesn't/won't show these symptoms, it'd be great to know I can disregard it as the villain.
Many thanks
