Okay sorry to drain everyone,
I have tried to look up numerous forums but cant find the answer (real answer is to go back to Tuner but leading to Christmas time its too hard to get in and the tuner is over an hour away)
Had my car tuned and ended up needing to change my timing chain so went with an empire elite one and all went well
however a couple of things are happening since..
the car still sounds like it has a slight rattle to it, to a stranger itll sound like a lifter but the mechanic is saying its just the timing chain because its heavy duty but I dont believe that fully
2) when in P and idling the car is shaky. Changed the o2 sensor (upstream one) and still happening and had changed the coil packs and is also happening
Mechanic said it might be spark plugs which is the next thing I do however I dont want to waste my time either as the car has only recently been tuned
Weirdly, when the aircon is on the shaking is very minimal which makes me think that when in idle its a matter of the car just being tuned to idle to low or do I have something bigger on my hands
Worse comes to it I can just go back to the tuner and take a day off work but I also want to learn as I go because it isnt something I have come across before and dont want to change parts for no reason
I am thinking it could even be a lazy injector
