Hey guys..

I just serviced my EJ8 Coupe (D16Y8 SOHC VTEC)

The car now has a very irratic idle, aka you give it a rev, it falls down to 1,000 RPM, then goes back up to 1,500 RPM, then back down, and up etc.

I used some Subaru upper engine cleaner on the Throttle body, and drove it after to purge it out of the car. New plugs, oil, filter followed.

I read this somewhere

) Did your Throttle Body get bored out at all? Is Air bypassing the blade?
Could I have covered the sensor in the intake manifold in gunk? thus making it fail and not pick up the air readings?
