Gl running rough as

[Glynn.]

lately ive been having a bit oftrouble with my gl, engine is not holding a steady idle, using too much fuel, flat spotting at different times, i know for a fact its running rich as we plugged it in to a diagnostics tool, but thats all the info it said
has going to just replace engine temp sensor, but dont know what else it could be
any help would be appreciated

[Glynn.]

well i replaced the temp sensor, blasted teh crap out of it with some subaru engine head cleaner foam stuff, has gave me my power back no flat spotting etc, altho she still idles rough and no minor backfires.............
any ideas lol

[Glynn.]

i do not know what a lambda probe is lol

Its just a fancy name for a 02/oxygen sensor

[Glynn.]

oh lol thats easy enough to fix its located in the exhaust hey?

[VR28LT]

yeah mate
just before the catalyic converter.

mightpick up a new one at work tomorow
it not running quite as rough as it used too, jut seems to use like 10litres per hundred kms
which is pretty damn bad imo

also have a look out for a vacuum leak.. i had a few issues with flat spots , bad mileage and rough idle.
turned out to be a combination of both (bad 02 sensor and a vacuum leak)

thanks for that bud

Probably a vacuum leak.
Cheak the plastic pipe that comes from the middle of the engine and goes to the intake and the rubber boor on the top of it.
