I just changed plugs--injectors--upper & lower intake & imt gaskets and got a code for high fuel rail pressure. Took off the fuel sensor and cleaned it and the code didn't return. Now I got these new codes the next day--I removed the manifold and the rear bank intake holes are saturated--I had bought a new fuel sensor from jagbits that I installed last nite but didn't start car as I am thinking the high pressure from before has the injectors stuck open?

Thanks for any help
