97 Supra Vision running rich

[tbueno]

I recently purchased a 97 Supra Vision with the fuel injected PCM engine. The boat is in great shape and runs well but loads up a bit when idling. The fuel pump went out and had it replaced at the dealer, they also replaced the TPS to help with the loading up but it did not help. Any ideas on what else it might be? Dealer said only thing left was the MAP sensor but talked to a mechanic and he said if the map sensor was bad it would run way worse than it does. Just wondering if anyone else has had a similar issue.

Thanks!

What is a Supra Vision? They made several boats in '97, don't think Vision was one of them.
