97 challenger 1800 cuts out at wot

[c4markee]

Hey guys.
I have a 97 challenger 1800 twin engine. The right engine cuts out or drops off or cuts out, it starts right back up, but at wide open it just cuts out / stalls. Cleaned the rave valves. Still does it.
Does not have grey hoses .
Seems to run at 4-5k just fine.
Any ideas?

did u check remote fuel pump?

I would start with checking over the hoses, for an air leak, cleaning/changing the filters... and then... the carbs probably need to come off, and be cleaned.

All the hoses look new- not grey, very stiff yet but I have been looking at each one all connections tight.
I changed the filters with some I picked up at the auto store, clear one .
Switched the hoses for each motor to the shut off valves ( rights left lefts right)moved motors.
Shut off the selector in question, motor still runs fuel still flows,slowly. Very noticeable difference. So.
How do I clean the shut off valve?
