Question

Replaced plugs ,b1 s1 oxy,cleaned fuel injectors, still comes back p0172 What am I missing Timing chain maybe

Answer 1

P0172 Fuel system too rich

Timing chain would not do it, it would set a cam to crank correleationship code, What cause rich condition are airfilter being plugged, ignition control module (which one time had a recall that is now expired) The promising cause of the rich running condition would be the purge valve,The purge valve would allow fuel to seep into the intake system ,check the hose of the purge se if there is fuel coming though ,
