    2005 Jaguar S-Type V8 4.2L Misfire



    When I start up my car, sometimes the car shakes, almost like I am running out of gas. I suspected a clogged fuel filter or something along those lines, but that is just a guess. I have no problems at higher RPM's like Street or Highway speeds.



    After the misfires, my check engine light comes up with multiple codes:

    P0300 Random/Multiple Cylinder Misfire Detected

    P0301 Cylinder 1 Misfire Detected

    P0302 Cylinder 2 Misfire Detected

    P0303 Cylinder 3 Misfire Detected

    P0304 Cylinder 4 Misfire Detected

    P0305 Cylinder 5 Misfire Detected

    P0306 Cylinder 6 Misfire Detected

    P0307 Cylinder 7 Misfire Detected

    P1313 Misfire Rate Catalys Damage Fault - Bank 1

    P1316 Injector Circuit / IDM codes Detected

    P0171 Fuel Trim too rick (Bank 1)

    P1111 Intake Air Temperature Sensor Circuit Intermittent High Voltage







    The car runs fine most of the time, this has only happened about 5 or 6 times in the last several months. It is now geting warmer and has not happened in awhile.

Check coil packs.
Also you may have air leak somewhere around the air inlet manifold - this can cause an imballance on low revs causing stall

Recently did engine overhaul but the timing chain gets loose after a few km drive and starts making noise nissan z24 single chain


the nissan z24 has a chain guard on either side of the chain
facing the chain the guide on the left is the chain guide and the one on the right is a guide as well it is a straight guide and when fitted should protrude slightly above the block face
it is held on the block by 2 bolts
there is also a small guide separate and above the adjuster bolted with one bolt in the head
the chain tensioner is below the lh guide and the bolts are tensioned to 53-89 inch pounds

2004 passat engine sounds like a deisel all of a sudden and has some engine lag


Hi, depending on engine fitted it is most likely the cam chain tensioner has collaped or failed. On a twin cam engine like a 1.8 t or a 32 valve V6 there is a chain driving a second chain in the rear of the cylinder head. These chains are tensioned by a oil pressure pressurized piston pushing on a bridge under the chain.

If it collapses, the chain/s become very loose and you will hear a loud clacking noise. It can also collapse due to low oil pressure.

VW is familiar with this problem and the repair involves first checking oil pressure, cold thro' warm. If it is around 85 to105 psi cold and 28 to 35 psi warm at idle, then this indicates tensioner piston is faulty or tensioner guide has broken off.

If oil presssure is good and engine is running synthetic oil...as it should ...then tensioneris suspect. I have also seen these engines with the screen under the tensioner partly blocked . If on removal of valve cover prooves tensioner has collapsed or guide shoe broken or warn then a new tensioner must be installed.

If oil pressure is too low at under 12 psi at warm idle then oil pump is worn and/or engine is worn. Also low oil pressure can be caused by fuel in the oil making it very thin.

If the screen under the tensioner is partly plugged up, then the oil pan must also be removed and cleaned out otherwise plugging will happen again.

To remove and install the tensioner a SST ( Special Service Tool.) is required to compresse the tensioner piston to allow it to be removed from under the cam chain and again compressing the new tensioner to be installed. Cams or chain do not need removing on this job.

Most import shops can handle this as long as they are equipped with the SST tensioner tool.

    3. Check that the tensioner pin moves smoothly when the ratchet pawl is released with a thin rod.
    4. The key of the crankshaft should be aligned with the timing mark of the timing chain cover. This indicates that the piston is at TDC on the compression stroke.
    5. Install the tensioner adapter assembly. Install the crankshaft sprocket and left camshaft drive.
    6. Install the left timing chain guide and torque the retaining bolts 14-18 ft. lbs.

I AM FROM A REPAIR SHOP IN MD. WE ARE CURRENTLY WORKING ON A 2006 CADILLAC SRX WITH A 3.6 ENGINE. THE INITIAL ISSUE WAS THAT THE CHAIN BROKE ON ONE SIDE. THAT CHAIN WAS REPLACED AND VEHICLE WAS...


the timing is off, take a good look at the reluctor wheel, make sure its not slipping. other thing is the tensioner, if the marks were all lined up when put together and they are no longer lined up after driving, then the tensioner will have to be replaced.
if you do not have the special tools to set the timing up, send it to the dealer and let them set it up for you, but your timing is off.

My 1990 nissan sentra has a noisy timing chain when running idle.


Your timing chain tensioner is using oil pressure to stay tight.Could be your oil pressure is so low at idle the tensioner just can't stay tight.At the next oil change you could go for a thicker oil and see if the tensioner keeps the chain tighter at idle.
