Any guru's on line feel free to respond.

Took an MY06 CS9 out for test drive this morning....sale pending satisfactory inspection and test.

Has had a flat battery for past 3 days, charged overnight. I let it warm up kept of boost and just ran smooth. Once warm pushed it pretty hard but no redline.

After couple strong runs to 6000rpm, check engine came on. No drop in power car drove beautifully. Pulled up and switched car off for minute and back on but light still there.

They're taking to auto sparky to get CEL checked. Any thoughts off top of head...would low battery charge cause CEL to kick in? Bugger all fuel in it too so low fuel pressure?? No rpm drop though.???
