Hey all, new here.
I've been struggling with this issue for quite awhile. I'm not super mechanical, but I've got a buddy who's an excellent mechanic.
I've got a 2008 500 EFI. The engine cuts out/misses at around 4200-4500 rpms, then comes back fine. (roughly around 18-22mph) It seems like it would be an electrical issue but he doesn't know enough about Polaris electrical systems. It's not throwing any codes.
so far we've:
replaced air filter
spark plug
fuel filter
I've seen where the symptoms can present as a worn cam. Last weekend we tore into the engine and he said the cam looked fine, and adjusted one valve. the rest of the valves were correct. Didn't fix the issue.
I just saw today looking around the forums here where it could be a tmap wire? Any thoughts? The problem is irritating the heck out of me and I just want it fixed. I don't want to keep dumping money into parts it doesn't need. That's not in my family budget.And I don't want to take it to a dealer and have them not be able to figure out the problem or fix something that isn't wrong. Other than that the machine is great.
If anyone can point me in the right direction it'd be greatly appreciated.
