Default Idle speed on 99 Turbo

After changing the MAF on my 99 2.0 Turbo the idle speed is too low.
The old one was spot on, but performance way down.
Is there an adjustment for the idle speed?

Try re-setting the ecu.

But this happened as soon as I changed the MAF and I bet if I put the old one back the idle would be fine.

was that a new maf you replaced it with?

after ecu reset the ecu will relearn, give it some time and see if the idle settles, should be around 750-800 on a normal ecu

although there might also be something wrong with your co2 sensor, located in the downpipe
