Hi Guys
I'm wondering what could do this. I noticed last week on the highway under hard acceleration it would puff out a cloud of black smoke really bad.
It would clear up and then I see a little trace of black/greyish smoke trailering at the tailpipe which never seems to go away under hard acceleration. It's a 1996 extended half ton pickup.
The engine light has come on sometimes when driving in the city or highway, but not under hard acceleration. It did not seem to make a difference in the performance. The engine light goes out by itself. It sometimes comes on and goes off quickly. The codes I managed to get was P0406 Exhaust Gas Recirculation Sensor A Circuit High. Doesn"t happen all the time. I checked the vacum lines and they seem ok all tight. Fuel filter was changed also recently but no diference.
