I have been having problems with my wastegate staying engauged well after the engine has warmed up. its thrown out two codes P0603 and P1248. I dont know if its linked with the touchy throttle but at the beginning of every gear the truck starts to waver with the RPM's making for a not so smooth take off. Whats odd is when im on the highway i can put in on cruise control and go without problems but when i take it off cruise and use my foot it wavers again. Any suggestions or advice?
