Hi, i have problem with my alfa :/
1. engine has rattle noise, when i bought it few months ago, it was nice and quiet, few days after purchase it started to rattle from startup, rattle is louder when revs go up..Also on 5th january i went home from other city, i was forcing car a bit on highway, when i started car next morning it was nice and quiet, next 2 days, on 3rd day i went to that other city, on toll booth it started regeneration (i had DPF back then) and from that moment engine returned that rattle sound...
2. vibrations on gas pedals and gear lever, for example when i keep some speed i hold my foot on gas pedal, i feel vibrations, which are more intense with higher revs..., also when i stay on red light i also feel vibrations on brake pedal and when i rest my hand on gear lever
3. Loss of power when engine warms up
4. Driver seat started to squeak on speed bumps...
Car has 170 000km on it (its real not false KM)..
I removed dpf, blocked EGR (via software, dpf filter is removed from its housing too), changed oil and filters too, previous owner did big service before selling, i fill it up with good fuel, when i was changing oil and filters, my mechanic reseted service, and we checked injectors while car was steady, 2 were in +, 2 were in -, values between -1 up to +1, or -2 up to +2, cant remember...
Also intake manifold is brand new
