Engine Frustration - Help!

[JordyG]

Hey guys !

So I recently purchased my FG XR6 Turbo, It is bone stock only 40,000ks with a mature previous owner.

now after only just getting it home and pulling up at the local service station only to notice that my MIL or engine light was on, and the idle had become very rough, consistently reving as if I was driving a v8 with a very lumpy cam.

So I took it to my mechanic and he said that the timing had advanced its self to far, and suggested to run 91 octane fuel so it would pick up on the nocking and pull the timing back its self.. now I have given a small amount 91 (not wanting to put to much through) with no luck as of yet.

Has ANYONE has this problem before? or can anyone shed some light on the possible Issue, as it is driving me insane.

Thanks heaps !

You have Warranty? It could be a few things that's the problem. Hard to diagnose this way..

[JordyG]

2009 so out of warranty. and yeah I can imagine, was hoping someone had the exact same problem ha.

Hang in there,someone on here will come along and help.

Did your mechanic plug in a scan tool?

[Kroozin]

Does it stay rough the whole time or does it come good sometimes?

[JordyG]

Yeah the mechanic used his scan tool, said all he could find was the advanced timing.

and yeah stays consistently rough basically the whole time on idle. if you hold a small amount of revs on it will idle fine.

with out sounding rude about your mechanic, but you need to take it to somebody that can diagnose it properly for you, running it on 91 will not rectify anything
