have a rev limiter? after installing the thermostat I was warming up the motor and when it got warmed up I thought I would goose it a bit it goes to 3k rpm but if you give t more throttle it chugs and hessitates really does not want to run any higher than 3k rpm while in park, I did a road test and it is just fine.
so just wondering whats up, if any thing might be bad
