Cp9a evolution 5 iacv
Good day guys,
From my previous questions and queries over the weekend we installed new id1050x injectors, brand new 02 sensor and new spark plugs. This made a drastic change on ecu flash because we now can configure an change the values.
However we are still getting an issue where there is an idle surge aka hunting where the rpm fluctuates on idle, when the car warms up the idle drops and the aem wide band drop from 12-13afr to 11afr and remains rich.
We decided to check the evo5 iacv where when tested it slowly goes in and out, so we believe it is bad and needs changing. Any advice on the replacement? As there are ones on eBay for around 40-80us.
