Do you mean P1478 – Rave valve open position not reached ?
I believe that was the code,
Octanee, my 1K turbo friend, where are you?
Sorry Sir and everybody else, Between work and life and never ending pile of crud to repair I kept forgetting to pop back in to update some replies!
How you been! Still got the old 1k?
OTHERWISE I took my fathers sled out today and I'm wondering if its somehow fuel related,? It did get a few lean pops, NO CODES, but i can pin it and it sits right at ~7900- 8k rpm so we know the valves have done their thing, it sounds good and crisp then bam it cuts out and drops to ~7600, climbs again to 7900-8k ish, does not overshoot, then it pops, cycle continues periodically, and if you can climb long enough ~10 seconds wide open it starts to do it more and more and loose rpm at that point and have trouble recovering, no way was the rpm OVER shooting causing it to hit the rev limiter as best I could see. When you jam the throttle it always had that kinda hesittation/ cutting out sound as it rev'd but it never had issues holding the rpm and climbing til this year. Sled has over 9k km on the chassis but had a new engine when we bought it, so thats where I'm wondering if its fuel, we did replace the plugs for last winter just because. He was on the trail earlier in the day and it just was cutting out left and right....
