Hi,
The car idling is very very bad it keep hardly running on idle, needs to be started by accelerating otherwise it just stalls.
DTC found related to downstream lambda sensor, I've checked the lambda and it looks ok.
emissions:
on idle
O2: 7%
HC: 600 ppm
Lambda: 1.3
CO2: 6
CO: 1.5
on fast:
02: 0.5%
hc: 40 ppm
co2: 12
New idle control valve, spark plugs and Coils fitted by garage.
Throttle potentiometer looks ok although it keeps on 2.2 volts on idle, is it ok?
Lambda front and rear looks ok,
Front lambda kind of try to switch but very intermittent.
any ideas what could be causing this problem?
Thanks
Daniel
