Re: Tank venting / periodic hissing noise

Yes, values seem to be ok. The lambda probe sends voltage between 180mV and 800mV at idle; water temperature was >95°C when I had the Marelli tester connected with the car.

I need to do an emission check next Monday, hope the car will pass the test.

Re: Tank venting / periodic hissing noise

No, it's happing only during driving. There is a also a hissing noise when opening the tank cover, but I think this is a normal noise. The car runs fine so far. The only thing that I could observe with the Marelli tester is it enriches the mixture at idle quite a lot. The values are still in the ran...

Tank venting / periodic hissing noise

I hope that someone here is maybe able to help. After 20-30 minutes of driving, I hear a regular hiss of about 2 seconds duration from the rear / from the trunk. The hissing goes along with the opening of the fuel tank vent valve, so whenever the fuel vapor is fed into the intake. I suspect there is...

Front brake discs >10/1992

It's getting more and more difficult to find a source that can deliver new brake discs for the Super/FL models. All the known brands (ATE, BOSCH, BREMBO) show nla.

Re: Buying advise needed, can't get it out of my head

I prefer the 24V version over the 12V - because I own one :D My car is retrofitted with the bigger air intake runners from a Q4 and it has 200 HP at the wheels (dyno tested)!

Re: 164 Q4 rough when cold and rpms drop slowly

Quite simple calculation: I = U/R = 12V/14.5ohm = 0.83 ampere I = U/R = 12V/15.9ohm = 0.75 ampere Difference is + 0.08A, which means +10,7% current and +10,7% load on the ecu. You have to decide, if it's dangerous or not. But I highly recommend not to replace the original injectors with the newer ty...

Re: 164 Q4 rough when cold and rpms drop slowly

Pro tip: newer Bosch injectors (red) with 4 nozzles for 3.2, GTA, etc. fit nearly out of the box. Good tip to kill the ecu! The red valves have a resistance of 14.5 Ohm, whereas the original valves have 15.9 Ohm. This results in 10% higher current in the ecu, which is not good at all... You could i...

Re: 164 Q4 rough when cold and rpms drop slowly

I would check the fuel pressure before removing the injectors, because it is simple to do. If there is your issue, you will save a lot of work. Further recommendation from my side: Check spark plugs and do the compression test on front bank at first! When the spark plugs are looking good and the com...

Re: 164 Q4 rough when cold and rpms drop slowly

Yes, you may have a few issues at the same time. Basics are checked, but: False air leakage is my favorite and needs still to be investigated. Take 2-3 bottles of break cleaner and spray it all over the intake stuff. Fuel evaporation valve could also be an item. Disconnect the hose from the plenum a...

Re: 3 Liter engine of Lancia Kappa versus 164 Q4

Kappa has two versions of the V6 24V. The oldest is comparable to the 164, the later version is comparable to 156, 166 and 916 engines. Since the Kappa use the same camshaft sensor, you do not need to change the right exhaust camshaft! The Super V6 24v has the same engine block as your Q4, only diff...

Re: 164 Q4 rough when cold and rpms drop slowly

There is a false air leakage. Bad injectors don't keep RPM up, they may be an issue of rough idle.
Spray break cleaner at every possible location and listen carefully.

1) You have to wait until the engine is completely cool and first cylinder is at TDC (in ignition stroke!).
