Cylinder # 3 has a misfire...#1) Defective coil on plug or the spark plug itself...#2) Contaminated fuel injector...See drawings below...The coil pack is the smaller of the two and sits to the rear of engine it is the most probable cause...Although the spark plug or the ignition wire (connection between plug and coil pack) could be at fault...so, before you invest in a new coil pack...Remove from both ends the wire from #3 and switch it with #2...if the fault code changes to p0302 that wire is bad...next Install a new set of plugs....Fault still present? replace the coil pack.....Unless recently changed new plugs and wires are a plus even if fault remains...saailer

SOURCE: 2003 FORD ESCAPE CODES NEED TO KNOWN WHAT THEY MEAN PO316 ,PO306

PO316 is misfire on startup
PO302 is misfire on cylinder number 2

To find arc-over, start car at night, and look in the dark at the entire routing of the plug wire. I have seen where there was a faint glow the full length of a plug wire.

At a minimum replace the number 2 plug wire. Make sure it is seated on both ends and clean of corrosion.

You either have a bad ignition module or a
vacuum leak,intake manifold,PCV Hose,etc
that effects cyl #3

Ohm Checking is for the 1980's

Todays tool is an oscilloscope, you won't
have at home.

Also Smoke the intake and EVAP System
for leaks (EVAP Smoke Machine)
