I have gotten this code usually after (or during) WOT to get on the freeway.
Engine seems to run smooth when not excellerating but seems to miss at WOT
or even accellerating at less than WOT. P-0201 = Fuel Injector 1 Circuit.
I've cleared the code and the truck runs fine till I WOT a few times. It
doesn't always happen with the first WOT but it has occurred 3 times in the
Is there anything I should look at before taking it in to the dealer?
Almost 98k miles on it, original fuel pumps.
Along with that code I get the P 0633.
