i have a 2005 escape xlt 4wd, it has a cylinder 5 misfire, ive changed plugs, and coils. new upper gaskets, new injector, still misfire. noticed tonight that at idle, it sounds like an old steam engine, ie. when the cylinder hits top puff of air. also have a backfire in the air intake. any help would be great. ive got a new pcm on order but would love to have it fixed before it gets here. :thud:

I have a 2001 and just joined this forum today to some advice on this. But my Escape is having cyclinder 3 misfire. It's been over a year, did u get it fixed yet or just get rid of the vehicle. I had code P0303 FORD - Cylinder 3 Misfire come up when I went to Adance Auto Parts to get codes read for free. Then I found this online:

 

P0303 FORD - Cylinder 3 Misfire Detected

Possible causes

Faulty spark plug 3

Clogged or faulty fuel injector 3

Faulty ignition coil 3

Fuel injector 3 harness is open or shorted

Fuel injector 3 circuit poor electrical connection

Ignition coil 3 harness is open or shorted

Ignition coil 3 circuit poor electrical connection

Insufficient cylinder 3 compression

Incorrect fuel pressure

Intake air leak

 

What does this mean? Tech notes The P0303 code means that the cylinder 3 is misfiring or is randomly misfiring. Start by checking for intake leaks and if no leaks are found the next step is to replace the spark plugs on cylinder 3. If the problem persists more tests needs to be done to diagnose problem, see "Possible Causes" What does this mean? When is the code detected? Engine Cylinder 3 is Misfiring. Possible symptoms Engine Light ON (or Service Engine Soon Warning Light) Lack/loss of power Hard start Engine hesitation P0303 FORD Description When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the Crankshaft Position (CKP) sensor signal to vary, the Engine Control Module (ECM) can determine that a misfire is occurring.

Not sure what to do since Ford doesn't make it easy to work on anymore.
