Front 2 cylinder on drivers side keep fowling
The drivers side of my engine keeps back firing and fowling plugs. I did a cam change with TREX and PRC springs with new pushrods and comp magnum 1.7 rocker arms. Question, Could the rocker arms not being adjusted right cause the readings on my o2 sensor to be going up and down so much? Any ideas?
