Hi guys, I am looking for some help with a couple of issues. Roush 342 with Holley 770 CFM Carburetor w/ vacuum secondaries and electric choke. I've had the car about 3 months.

1) I've noticed lately, and out of no where, that when the engine warms up and you take off at any speed, when you go to shift that the RPMs will not drop back down to idle. They will stay at 3k. If you tap the throttle, RPMs will then reduce down. It's almost like there is a cruise control built in. Something is sticking somewhere? This issue was not there when I first took the car. (EDIT I guess it is more likely to be a throttle cable issue and not part of the carb... but wasn't sure if there could be some kind of vac leak, etc)

2) There seems to be a bog at around 2k RPMs (going more off of sound than a lack of power) and once speed increases it goes away and you are at what feels like full power. I have changed the plugs, but not the wires. I was thinking it was more of a carb setting than anything else?

Thank you for your help!
