I think the problem with the exhaust valve, spark looks good, if you have already inverted candle and injector, little chance....to try dipstik conferm little push due to bad explosion. The compression test as was done? with pressure gauge in start? You have the possibility to do the test with WPS50...

Hello Steve, as you have reported is a test "delicate" and easy to get wrong reading, a question: Why connect the WPS in series with the bleed screw open and connect the sensor with T-fitting, drain well measuring chamber and then let drain closed? The measure is not real? Leaving open the bleed scr...

looking at the files you have added to your car is out of phase by about 17 ° of crankshaft, the command of the VVT is similar varies little, the signals of the intake and exhaust cams are equal to the reference signal (library). I took the two signals that you provided, I took as a reference signal...

Terbo Thanks for the photo, I hope someone can explain to us the wave form in the intake manifold "strange" caused by an exhaust valve burned.
greetings

The test dipstik, shows that you do not have problems of piston rings, also confirmed by the fact that does not smoke for oil consumption, pressure testing exhaust, you confirm that you have in the cylinder 2 poor combustion, look at the picture: mancate accensioni_.jpg The abnormal shape of the wav...

If you want to know if the problem is a piston or an elastic band, uses sensor wps500 with maximum resolution and controls the pressure of the engine block (crankcase ventilation), from oil dipstick hole, the pulsations caused by blow-by must all be equal, if a is higher is because of elastic bands ...

One oddity in your acquisition are the voltage levels of the camshaft position sensor, the stage down is not zero volts (ground) and the upper part of the signal is about 6 V, or is usually 5V or 12V. The probes are connected correctly? The power of the sensor is correct? The mass on the sensor is c...

You have rightly entered, the command by the engine control unit, the current consumption, but lacks the voltage signal of the primary, to better understand acquisizione with would need a longer time and at least one strong Expedited, then zoom in on the signal are controlled by signals .
Greetings

Best wishes also from me, I hope you are well past the holidays and some days you do not plan to work, but only to the family.
Merry Christmas and Happy New Year

If I'm not mistaken, in the database on-line there should be a signal vs crank cam for this car, unfortunately I do not have now connected Pico scope and do not have access, but you can try. A correction of + - 3 is not small, it remains always on cylinder 3 the problem could be mechanical, maybe an...
