just got a new (used Motor) and it all seems ro run great but it refuses to Idle. it boost great and pulls very strong but when I pull to a stoplight or sign it seems to bump between 500 and 750 RPM. I have replaced the Idle speed sensor which Improved things a little bit but its still sounds like Im running really long lobed cams. it also has a small issue with throttle responce when I am driveing at low RPMs IE Parking lot. anyways any thought s on where to look next would be greatly appreciated.
