badger Posted June 19, 2006 Share Posted June 19, 2006 I've owned my supra sz ( N/A manual ) for a month now and i've noticed the acceleration seems to hold back untill 5200rpm then it really starts to fly. plus in low revs i can hear it pinking. It has a HKS air filter in the box, but i dunno if this would affect it, everything else is standard. Oh, and i've been running it on normall unleaded not super, bit skint at the mo. Any ideas on what could be doing this? Link to comment Share on other sites More sharing options...
Matt Harwood Posted June 19, 2006 Share Posted June 19, 2006 How old are the spark plugs? - Also worth getting your timing checked? Link to comment Share on other sites More sharing options...

Ian C Posted June 20, 2006 Share Posted June 20, 2006 If you've been running it on a higher octane for a while and suddenly, in hot weather, switched to lower octane, it might be having difficulties? As much as I hate to offer this particular solution up - try resetting the ECU... -Ian Link to comment Share on other sites More sharing options...
