Problem occurs mostly while going uphill at a high speed. Going up at about 70mph and it will drop to 40mph. Also rough starting and has some hesitation and stuttering from a stop. It was throwing a code for fuel being lean so I replaced the 2 upstream o2 sensors. Replaced plugs and wires, checked fuel pump, ran some seafoam through and checked fuel injectors. Someone said it could be TPS or clogged catalytic converter.
have the same problem?
