P1090 CEL code
Need some help from fellow SVT owners....
I have an 02 SVT with many bolt on's and a Predator tune from Tom. Everything has been great for the last year with my love BUT about 2 weeks ago she started losing power in the upper RPM range (5K to 7K) and stumbling real bad. The symptoms only start after the car has been driven for a long period of time. The CEL light came on and gave me a code of P0190 which is the Fuel Rail Pressure sensor. I took her into the dealer where a friend of mine works and no problems showed up on the computer. I went ahead and purchased a new Fuel Rail Pressure Sensor ($78) and installed it BUT the problem persist. I have had all TSB's performed on her in the past ( new manifold, fuel pump, injectors, AFM ) Any and all help/suggestions are welcomed. Thanks Joe lwnslw@bellsouth.net

you also may want to clean the MAF sensor carefully and some injector cleaner next

i dunno, maybe check that the fuel rail is screwed down properly and that all the injectors are pushed in correctly and not a little loose. ?
