E36 323i low power

Hi guys

I've been struggling with my e36 for some time, it just feels sluggish however very smooth no jerking missfiring etc.
I replaced various items such as the fuel pump, camshaft sensor(original), vanos seals, 328i exhaust and did the fan delete mod...
None of the above made any difference whatsoever :blueCry:
I've read my codes using inpa and nothing comes up.
I checked the voltage reading from the lambda sensors while the car was idling(hot) and got between 0.15-0.23v on both of them using a multimeter.
Interestingly I unplugged the vanos solenoid and it never generated a fault code as it did when I unplugged the lambda sensors ?

Any info or tips appreciated
:ty:

I have a 323 e46 and had the sam problem after driving and starting again absolutely no power. I had someone check the fault codes and replaced the airflow meter (sensor) and the intake camshaft sensor and all my troubles came to an end.

hope this helps.

I would hazard a guess at low compression due to valve guides leaking.

If possible do a test and see what figures you get.

After you did the vanos seals was there an improvement in performance?
If not a discernible improvement I would again hazard a guess at incorrect seal fitment/worn vanos piston chamber/ cam setting.

Nothing noticable after changing the seals, it seems as if there is a electrical fault or short somewhere.
If I go over a bumpy patch of road the car is like a rocket for while until i hit the next bump then its back to being lazy...
I'm getting annoyed with this car

Ride more bumpy roads then.

Sounds like a dud solenoid for my money and it will not always show up on INPA

However the possibility of incorrect seal fitment and cam setting should be investigated

I removed the solenoid and put 12v on it, it pushed the piston out.
Is that the correct way to test it ?

Nope....you may have burned it to toast.

The solenoid is tested for resistance not voltage.

Replace the crank position sensor I had this issue on my E36, no fault codes showed up either. :=):

CPS typically break up on the higher rev range.

IIRC... The last time I checked, this car has a pirate Crankshaft positioning sensor fitted. I bought it like that.

Hi Theo

On Friday I forgot to mention you can get the solenoid repaired, pity I threw my old away as it was still repairable but I guess it's best you get a new one.

Please let me know if it makes any difference...
