I looked into a few forums on here and decided to clean the throttle body in hopes of getting more kms/ litre. Took throttle body out and cleaned it with throttle body cleaner, put back in and started car without air intake attached, (incase wasnt fitted right etc save taking intake off again), and thought that by manually opening throttle plate by hand would just rev engine. Stupid I now know. Car stalled straight away but started up again first pop. Seems to be running alot smoother now but a couple of times at lights has a light ticking noise coming from engine since doing this. As soon as I increase revs slightly tick disappears. So just wondering if this could be caused by me opening throttle plate and damaging something in process. Also idling at around 600 revs Link to comment Share on other sites More sharing options...

Just its never made this noise before but I dont think it used to idle this low either Link to comment Share on other sites More sharing options...

It'll be idling there because you've cleaned it, rather than because you pushed on it. Link to comment Share on other sites More sharing options...

On another note, diffs whining like hell, have read that au diffs are compatible and better, being 4 pinion as apposed to ba 2 pionion, thoughts?

Bryan014mb New Member 9 Member For: 5y 9m 9d Posted 25/04/19 07:35 PM Author Share Posted 25/04/19 07:35 PM Have just got through first tank of petrol after cleaning throttle body and am only getting 6kms to a litre. Does the map sensor need cleaning if its a pressure sensor? All the spark plugs were replaced not long ago, will try changing fuel filter this weekend, any suggestions will be much appreciated.

If you piss that pod filter off you'll probably improve your economy and power a bit, a pod filter floating around in the engine bay is going to be worse than the standard intake set up.

Bryan014mb New Member 9 Member For: 5y 9m 9d Posted 26/04/19 02:37 AM Author Share Posted 26/04/19 02:37 AM Is there a way to test the o2 sensor with a multimeter before buying a new one? Link to comment Share on other sites More sharing options...

If you don't know how old the sensor is, I think you'd be doing yourself a favour even if it isn't the cause of your current issue.TI Performance stock Bosch sensors for $49.https://www.tiperformance.com.au/products/bosch-o2-sensor-suit-au-ba-bf-fg-falcon-sx-sy-sz-territory/?gclid=CjwKCAjwtYXmBRAOEiwAYsyl3Fcj0UQ3Ph0ymTFKoyqJbSSN4lCA8uF20NEQgVVAOfVZmRgk7HMwhhoC3cwQAvD_BwE 2 Link to comment Share on other sites More sharing options...
