Went out this morning.
Car starts right up.
Idles rough.
Let it idle without touching throttle pedal.
For in excess of five minutes.
Idled normal test drove fine.

Checked obd code after clearing three days ago.

Pulled an A2 fuel- 3-2-2 AMF faulty wiring.

Disconnected battery ground.
Unplugged maf (amm)?
Sprayed with electronic contact cleaner port connections.
Visually inspected connector pins- they all appear to be ok.

Replaced connector.

Reconnected battery cable.

Started car- because the engine was warm no stumble,stall, hesitation

With engine off key off
Disconnected maf (amm)?

Car would not start with maf (amm) connector disconnected.

Reconnected and started right up.
Where do the wires from the Maf(amm) terminate. At the ecu or the ezk?

Anybody have ny luck removing ecu and cleaning connectors?
