Hello everyone!

Please help me!
I have very strange issue, when there is warm outside my stilo works like a charm, but when is getting colder (about +10C or lower) i'm allways getting next faults, but they dissapear after some time and at next day they appear again.

Faults:
P0460 - Fuel Level Sensor Circut
P0335 - Crankshaft Position Sensor A Circuit
P0204 - Injector Circuit - Cylinder 4
P0638 - Throttle Actuator Control Range/Performance (Bank 1)

Faults appears not immediately after engine start, they apper after some time when a have revs ~2000-2500 on 2 or 3 gear .. when engine got some load. Engine starts shaking, faults appear, 4-rd cylinder turns off (as i think) and after that no shaking.

All the time in the spring and summer Stilo work great, but in Fall and Winter .. i have these fault. This is a second year i fight with this faults.

P.S.
Injectors are clean and working great.
Injectors wiring is new.
Throttle actuator is clean.

Please help me .. i'm tired

Either you have a weak battery, or a coil is damaged. Coils are expensive, but I guess that after installing a new hagh-amp battery and new coils, the car will be as new. Try switching coil from cylinder 4 with 1, and see if the fault moves with it.

Switching coils not moving fault. It still on Cylinder 4 ..
I don't think this is a battery because it faults while driving, so power comes from generator, not from a battery.

Power still goes through the battery... and if it's damaged, the alternator will work hard to keep the power up. What's the voltage measures on battery when:
- Idling with park lights (at least 13.7 volts)
- Stopped (should be above 12.6 volts)
