My truck is a 5speed, egr is opperating normally and I scoped the 02 sensor and everything is working I guess i didnt fully explain my issue, the truck when sitting still would idle fine, when you would press the gas the rpms would max out at about 1500 rpm and alternate between 1500 and 900 at about 1 second intervals a little faster when you floor it, once you got the truck to move the engine would act fine until you came to a stop and it would start hunting again when you pressed the gas.
