This is a 98 s320 , I recently did the head gasket to fix oil leaks
.. drove it a few blocks and it died , finally got it to restart ... and pulled into auto parts store to read codes ... after checking codes engine revved up and down .. And wont accelerate.. after checking several connectors , I try one last time , and it's running somewhat normal ... so I drive her home, I try again to start it and I'm back like before ... un drivable reving up and down ... 1580 and 0100 codes ... idle control , and maf ... also a have a bas asr light comes on while it's not running right ..

Where should I start? Should I remove and clean Valve body ?

Thank you
