Question about 2002 Jeep Grand Cherokee
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.
