Question about Jeep Cars & Trucks
2010 Jeep Grand Cherokee 3.7L
low combustion (low piston velocity, low piston accelerations)
that is what it does and means.
or low compression (cylinder)
bad spark or weak
or bad fueling (too rich misfire, so does too lean)
that is how it all works! all OBD2 systems, do this.
P0301 and P0306
is that heard to spit out?????? the scan codes, why?>
it can be as simple as.
spark plug 1 and 6 bad, H3LL all 6 bad. ever do a tuneup in 6 long years?????
spark boots bad number 1 and 6. ;cheap fix. buy them.
if you had done the turn up first, the boots would have been carefully inspected by you, and passed or failed, burned = fail)
or the cops bad. $$$$$$
or you gapped the plugs wrong, not reading the SM on gap spec.,
why not use new spark plugs. and gapped right.
SM = service manual,
what told you 1 and 6
must we guess that?
No miles on engine stated, all we know is 6 long years of service.
no miles since, a full tuneup, spark parts. tops list./
same answer on tuneup for 100 years now.
nobody does them. then wonders why spark plugs dont last life of and engine, sigh. "they dont"

Ignition coil one and six or course.The 3.7L uses separate ignition coils for each cylinder. The one-piece coil bolts directly to the cylinder head. Rubber boots seal the secondary terminal ends of the coils to the top of all 6 spark plugs. A separate electrical connector is used for each coil.
Because of coil design, spark plug cables (secondary cables) and a distributor are not used.
Two knock sensors (one for each cylinder bank) are used to help control spark knock.
The Auto Shutdown (ASD) relay provides battery voltage to each ignition coil.
The ignition system consists of:
² 6 Spark Plugs
² 6 Separate Ignition Coils
² 2 Knock Sensors
² Powertrain Control Module (PCM
