I just bought a Vectra C 2003 , 1.8 petrol( i don't know where to look to see what is the code of the engine) .
I was very happy with my car the first 2 days but yesterday I saw that check engine is on and when I start the car it loses engine idle but not very badly then when it warms up it's okay. I've read the codes with the break and acceleration method and it gives me :
-P0170 Fuel Trim Malfunction (Bank 1)
-P0134 O2 Sensor Circuit No Activity Detected (Bank 1 Sensor 1
-P0110 Intake Air Temperature Circuit Malfunction
-P0335 Crankshaft Position Sensor A Circuit Malfunction
I am very sad because of this problems. Can someone tell me what is the reason? Is it the Maf sensor ? Lamda sensor or the egr? Or is something worst then this
Please help me !
