It could be the co2 sensor, but have you thought of having a cylinder leakage test done?? A competent garage should be able to perform this test for you. Basically they pump compressed air into each cylinder on the firing stroke, in turn, to establish that all is gas tight. If you have a broken piston ring or leaking valve, this will show up as a leak and could explain the rough running, especially on number five.

Code p0019 p0018 p0008


P0019: Cam/Crankshaft Pos. Correlation Sensor B - Bank 2
P0018: Cam/Crankshaft Pos. Correlation Sensor A - Bank 2
P0008: Engine Position System Performance (Bank 1)

P0019 & P0018
- Dirty Oil
- Engine mechanical problems
- Timing belt jumped teeth

P0008
- Engine mechanical problems
- Incorrect timing chain
- Stretched timing chain
- Failed camshaft actuator or actuator solenoid

The Engine Control Module (ECM) monitors the position of both camshafts and the crankshaft. The ECM performs a test for misalignment between both camshafts on one bank of the engine and the crankshaft. During the test the ECM learns the position of the camshafts and the crankshaft. While the engine is idling, the ECM compares the position of both the camshafts and the crankshaft with the learned value. The ECM will set the P0008 code if both learned values for one bank of the engine are exceeding a calibrated threshold in the same direction.

1999 malibu 3.1 clyd 5 missfire and now random missfire oil light is on lfters very noise runs rough


Have you confirmed there is no oil pressure and the oil level is full on the dipstick?

The oil pump is turned by the oil pump drive located under the throttle body. The oil pump drive is run of from the cam shaft. It is not uncommon for the camshafts to break on these engines.

It may not be a bad idea to pull the front valve cover and turn the engine over by hand to see if all the rockers are moving.

My 2000 lincoln ls feels like it has a misfire while idling @ stops. excelerates fine until it hits between 40- 50 mph. then has same feeling of the misfire or low power. then once it reaches over 50 mph...


Buy one new coil from auto parts store $59.00

Walk it one cylinder at a time

Why would you swap coils,obviously one
of them is bad.

The one you took out of #5,find it ,and put in the
new one there.

I would put in new OEM Plugs.
They are a special tip just for the LS
at least on ones newer than yours
They are NGK even though they have motorcraft
on the ceramic shell.

Clean the throttle plate and MAF with the two
CRC products for that

I wouldn't rule out a bad EGR Valve as another issue,
though not related to the misfire issue

Try running some fuel injector cleaner through your fuel tank. What you may have are a couple of plugged or missfiring fuel injectors. I would suggest checking all of your wiring to your injectors to insure good connection, replace your fuel filter and check for vacuum leaks.
