Hi All
I've got a 98 B4000 (4.0 L) - it has the CEL light on and originally it was throwing P0171 and P0174 - probably like that for 6 months. After checking/cleaning/swapping out MAF, fuel filter, PCV and PCV elbow, I think I've come to the conclusion that the intake gaskets need to be changed, but I've been kinda lazy to start it. Well, last weekend, after changing oil and filter, the truck starts to idle very rough, drives rough/hesitate and has been progressively getting worse. I checked and cleaned the plugs but its still doing the rough idle/drive. I took it to Auto Zone today and found out that it is also now throwing P0304 and P0133. Is this all related to the possible bad upper and lower intakes? How serious of a problem is it? Any help would be much appreciated!
