Hi Guys,
Had my 1999 2,5V6 Omega out drifting today. All went very well for first few hours but all of a sudden I noticed a power drop (water temp gauge was up at 100 degrees), she would barely spin the wheels in first never mind second. Engine revs out but was slow to rev and felt sluggish, almost like a misfire. The engine management light also came on however I've no code reader so no idea what it is... When I switched the engine off and on again the light went out but would come on after 5mins... no other symptoms.
I also swear the problem got less severe when the engine was cooler. Problem is not that she's not road legal and I can't test it (legally) till the next drifting event.
Can anyone recommend a code reader to use (I'm used to VAGCOM/VCDS for my VW's) or any ideas what the problem could be. Also will the code remain logged if the battery is disconnected? I disconnected the battery when packing her away and forgot that it may wipe the memory of the ECU :-/
Sorry for so many questions

:-/
Thanks a million in advance
