slow deceleration,idle 500 rpm ,on M60 engine
When i press the throttle to over 3-4000 rpm , the deceleration is to slow.
I know this type of engine and i know how this engine must decelerate.
Other problem (probably the same cause)is that the idle runs on 500 rpm .
The slow deceleration problem is more visible when the engine is cold.
I test with carb cleaner for vacuum leaks, i didn't find everything.
The pcv valve has only 30.000 km .
The injectors are ok.
I have a LPG sequential system , and the engine it works identical , on LPG and fuel.
I have tested with other MAF sensor and other ICV .
The oil consumption is about 150-200 ml on 6000 km.
Oil type 10w40 bmw.
