I took my 93 in for the state inpection and couldn't believe that it failed.
It failed the Nox(ppm) on both the high (25mph) and low (15mph) speed
emission results. Am I correct to assume that the engine is not burning the
fueling efficiently? Back in October I replaced the original fuel pump with
a new 155 ltr/hr fuel pump. Could this be the culprit? Should I intall
check the fuel pressure and install a fuel regulator if pressure too high?
New wires and plugs (all Ford OEM) recently installed as well. Please
advise.
