How to Diagnose Your Engines Skip

Sometimes it's easy to tell if your engines got a skip. Other times its not so evident that a skip is what's causing your engine problems. Even when your know its a skip, deciding on which cylinder is the problem. This how to makes finding that problematic skip easy as pie.
Instructions
Things You'll Need:
infrared thermometer
Step 1
First thing you need to do is get yourself a infrared thermometer. Sounds fancy but they are not all that expensive, you can find them for under 50 dollars. These things are handy for so many things, trust me you will wonder how you ever got along without one.

Step 2
Now you'll be putting the laser of the thermometer on the exhaust headers where they meet up to the head so make sure you have a line of site to all of your header pipe ends. This works on manifolds as well but not as good. Its still the easiest way to find a skip either way.

Step 3
Now just locate the skip. To do that start the engine and quickly go under the hood with your infrared thermometer. Check each cylinder temperature, the cylinder with the skip will be cooler than the others around it. This works great because it will show you if you have a dead skip or just a cylinder that is running a little cold, all in a matter of mins. Information like this is very valuable for fine tuning and getting the most out of your engine.

jeep grand cherokee crankshaft position sensor replaced but still given a weak spark


the coil. ? older post.
the PCM reports even one drop out of 10 , on the CKP or CMP sensors. 99.9% of these changed are good.
why not tell me what you have,? full symptoms and evidence.
got P030x misfiring? are you even using a scan tool,? or working blind.
may be its the coil.?
can can you feel the misfiring.c
can you see the engine shake? all of this is evidence.
do not miss out on that.
does the scan too shop pending misfire codes?
stored codes, or codes while driving, learn to use the scan tool.
do a 60k mile tune up yet?
your engine is not COP coils like the V8
its COIL rail that is a COIL pack with 3 coils inside
that runs 2 sparks each called WASTED park.
so did you try new sparkplugs(dah)first then new coil pack wires HV
next , then a new coil pack last.
start with the cheap spark plug and wires, (called a tuneup)
then pop for coil pack./
misfire can be clogged or leaking injectors too, and that ill skip
with out you using the scan tool fully.
