2007 Sunesta bogs down

[1946flyer]

Hello all, new to forum. Looking for help with my 2007 Chaparral with 5.0 Volvo Pena that will start fine, idles ok, and will run fine at higher RPMs in neutral but when you power up under loads I can only achieve about 2000 RPMs! I have been told could be the anti-siphon valve or exhaust temp prob! Any other ideas would be greatly appreciated!

Hi there, is your engine fuel injected or carbureted? Any engine model numbers handy?

At this point, I would recommend confirming that your fuel system is within specifications.
