I recently installed the sb66 turbo. Everything ran perfect. Lastnight, i installed the ddp 90hp injector nozzles and now there is a problem. I test drove it and it ran good but about 2 miles up the road the check engine light came on and lost all power. It almost sounds like its running on 1 cylinder but then it kicks back and runs good and then beack to crap. Any advice to what this could be? I pulled the codes and they are p2146, p0243.

 

P0243 Wastegate Pressure Control PWM
P2146 Bank 1 (Cylinders 1-3) Shorted High Or Low

Sounds like a wire loose or rubbing inside the valve cover. Or a connection problem for the injectors.
