I have a 2003 ford lightning and at first it starting with a small miss at idle and misses at WOT. Eventually it started doing it under a load and have me a code of bank one running lean (but why) the code was cleared and then came back with a camshaft sensor condition code, i replaced the camshaft sensor and the crank sensor while i was at it, but problem still persist. any help?
