i have a 2000 ford expedition 5.4 and after doing a complete tune up (plug,wire,vac hose,filters and pvc)and put headers and dual exhaust on. i discovered that check engine light is either blown or unplug (bought at a used car dealer).so it was running funny, ran the codes and got P1151.i was wondering if an exhaust leak at the header to the down pipe before the first o2 sensor would cause this?
I'm having a hard time getting the exhaust to seal up any info will
help thanks
