Hi all,
my friend's Pulsar GTI-R (SR20DET) has an issue with it's idle, with the car intermittently revving with no throttle input. We think it could be MAF or lambda sensor, does anyone have any ideas? Many thanks.
The problem with your friend's Pulsar GTI-R might be due to the MAF sensor or the lambda sensor. Here's what I'd suggest checking:
MAF Sensor: Make sure it's not dirty. Cleaning it might fix the idle issue.
Lambda Sensor: See if it's working right. If it's not, it can mess with the idle.
Vacuum Leaks: Check for any leaks in the intake system. Leaks can cause the car to idle weirdly and rev up.
