OK i just bought a 93 Honda Prelude VTEC. I will let my car sit and run for like 5-10minutes. And when i take off and hold the gas at a steady speed it starts to sputter and when i give it more gas it hesitates. It only does this for like 30 seconds to a minute. And i know that i need a new o2 sensor which im getting Teusday... And i was wondering what could be causeing this? I would appreciate the help. Thanks

 

A tune good tune up might do the job, and if it's been like that for a while you might need to reset the ecu, cause it got used to the way it was running.
