Are you near any tuners that could diagnose it then take it back to Expensive Daewoo to fix. Link to comment Share on other sites More sharing options...

Get a GOOD service done and if by a site sponsor (people who know what they are doing) chuck it on a dyno to see whats join on. It will cancel out a lot of things by doing a service, change the coils as they are cheap.. Valve springs are about $800-$1000 fitted, and then if that's not your problem you'd be spewin..
