2005, is old, the cop boot are bad too that old
boots are $15 each an 10x less than coil + boot.
best is replace the,
spark is first, cant burn fuel (gas) with bad spark.
my guess if you scanned it , you'd see P0300 errors, means all fail.
or see P0301 and only coil #1 or boot is bad.
or injector #1 is bad. scan it.
not scanning the PCM means wild expensive gue$$ing
beg,barrow,rent ,buy the tool or get is scanned in any shop USA>
most COPs replaced where never bad, HV wires/boots/plugs yes.
there are other causes.
- bad engine, (cant be fixed with new cops or injectors)
- bad spark
- bad injections means fueling problems
I say why fear scan tools?
the pay for them selves, that first time used, it is now a free scanner.. see how that works? ROI?
saved from shop labor
saved from THROWN parts not bad..? Do it first .
even blown fuses,(o2 sensor fuse blown)???? check fuses.
