Hi guys,
New member here first time question... I own an 03 explorer limited 4.6 awd.. Getting codes from a s.e.s light po059, po135 and po155.. All 3 codes came after replacing the intake manifold due to a coolant leak at the thermostat housing.. Also replaced the intake manifold gaskets. While I was in There I also cleaned the intake runners in the block with a spherical wire brush that was attached to a cordless drill and a can of carb cleaner.. Car runs fine, idles a tad rough but no other issues.. Thinking that all of the varnish and carbon build up from the nasty intake runners? That have possibly fouled the o2 sensors? Or do I need to try the seafoam clean process? Any suggestions would be great. Thanks
