My 2002 Sable misfires on one cylinder while cold

have a compression test done as there may be a valve problem or a hydraulic tappet fault that is holding a valve open

The Codes 302 & 303 are cylinder misfire codes,google them

Spark Plugs have nothing to do with misfires,it would be rare in
a life time if one ever failed to fire

Forget the 316 just misfires on start up

A repair shop would be your best choice without knowledge,
reference material & test equip

Ignition coil or vacuum leak problem

The PO 316 is still misfires om first 1000 revolutions
so the shop did a poor job for you on resolveing the
cylinder misfires

Try a diffferent shop

Have to clean the MAF Sensor & replace upstream
oxygen sensors if over 100,000 miles

Need the correct oem spark spark plugs/any brand

No reason the gas filter should be clogged unless it was in
the car for 10 years

Fuel pressure should be checked

Need to check for cylinder misfires on a road test of 20
miles or more with professional software in Mode#06

Can't believe some the lame answers here. Anyone having this issue check the PCV hose where it attaches too the air intake, the rubber breaks down and develops a leak. But these engines also have wiring issues that causes crankshaft sensor to fail at startup or under 1000 rpms causing the computer to shoot a code and trigger the engine light. I have these issue cause the above problem.

Hi

P0305 is misfire in cylinder #5.
P0306 is misfire in cylinder#6.
P0316 is misfire on start up.
Have the plugs on those 2 cylinders, and the 2 fuel injectors checked, also check for spark from the coil on those 2 plug wires.

Please get back to us if you have further query or else please accept the solution.

Thanks for contacting fixya.com

Well. Your car has a 6 cylinders, the front cylinders are 2, 4, 6
the rear cylinders are 1,3,5.

Try it. and if that cylinder has a misfire, probably could be a spark plug,, wires or distributor.

good luck

P0302 IS MISFIRE ON# 2 CYLINDER P0316 I THINK IS KNOCK SENSOR BUT IM OLNY 90% ON THAT

could be a burned valve. Did you do a compression test? What was the code specifically, P0303?

replace the coil it is most likely bad. observe the engine at night or in a dark environment and proceed to use a spray bottle to lightly coat the coil pack for that cylinder number 3 and if you see an arc at the coil or any where else this will confirm a bad coil but even if you don't see any arcing it still may be a weak coil.

Yep, bad plug or wire.
