When idleing it normally does all right at first but when driving at any speed it shakes and speeds up and slows down uncontrollably i bought a code reader and it says cylinder 5 misfire bank 1 and 2 are too lean could this be a fuel pump problem, ive placed a check valve in line of the fuel filter because i thought it may help and no difference was noticed, and there is no vacuum leak on cylinder 5 ive replaced spark plug, injector, and coil
