I have an 04 territory with 152000km it developed a miss fire suddenly last week diagnosis ended up being no3 coil pack despite it not showing anything on the diagnostic equipment. It ran well for a day now it has developed the misfire again although not as bad. Is there any other common causes for this problem? Plugs were changed 2 mths ago as well

Sorta the same issue with 3.0 '03 Escape

Mine was solved with a new coil pack on #3

2 months of messing with it

Mostly pulling hills with a little pedal--1-2 second bursts of stutter. Just here and there, at other times

No Check Engine Light. No codes. With mine, or the auto part's
store scanners

Other suggestions I had along the way were: New Plugs--gapped properly, not out of box, and slapped in!

New Plugs--2nd set Motorcraft, not Autolite

New boots and springs on coil packs--possible fire jumping thru a cracked boot

New air filter

Clean MAF

Replace MAF

Clean EGR

New EGR

New TPS

Clean IAC

New IAC

5,000,000 Vacuum Leak Searches

200,000 pinched wires/ messed up wire searches

Almost wore out the connector, on my scanner!

Multiple fights with Wifey who drives it

Made Multiple attempts to get the Tech School to do a ride around with their Super Computer.$25 Donation!

Fell thru each time---Drama within the Department

IT WASN'T GONNA WHOOP ME!

Attempted to "OBTAIN" a salvage yard used coil pack (I was gonna swap it thru the system, till I found "THE ONE"),

This led the salvage yard owner to scan for codes with a better scanner. NONE!

. His scanner did pick up a "STORED CODE".#3!

Spent about $80 more for a new one

FIXED!

I did not mind the expense along the way. CHEAPER THAN A SHOP FOR ONE ISSUE.I performed multiple operations!

I now have updated parts on a 100,000 mile vehicle. PREVENTATIVE MAINTENANCE!

I NOW HAVE SPARES FOR FUTURE TESTING!

IT DID NOT WHOOP ME!
