- 03 exp. sport trac xlt4x4
hi, I'm new here. I found this helpful place by accident. I was trying to fix my '03 sport trac. check engine light came on a while ago, then it started stalling when you start it. then it got a rough pulsating idle. steadily getting worse. Found 4 codes p0171,p0174,p2195 &p2197. Kinda hard to think both O2 sensors would fail together so I started looking for loose conections or a vacum leak. The air raid throttle body spacer I installed is 1" thick, which moved the air intake hose forward 1", which finally pulled the pcv pipe off behind the mass air sensor. started truck & plugged it in and instant fix. 3 small hose clamps will keep it from happening again. Thanks for the good ideas in the other posts
