jtmitch54 Posted July 17, 2013 Share Posted July 17, 2013 New to forum, Hi there! I have a 2001 S-2000 with a complete (dealer installed) GReddy turbo kit including big injectors, blow off valve, fuel pump, etc. It includes a GReddy Ultimate engine management system also (and auto shut off count down timer). My issue is that it occasionally stalls when I am coming to a stop. I re-start and it finds 1K i smooth dle speed. Give it a throttle bump and it comes down to idle and stalls. It does this hot or cold, and I also notice sometimes shifting into second gear I get surging until I give it more throttle. It does trigger check engine but it just codes misfire and I clear. Car runs beautiful and smooth at all other rpm's. Any idea what might be the issue? Could it be IAC or TPS? Not easy to figure out with all the turbo stuff and on-board engine management. Any suggestions or shared issues/solutions appreciated. Hard to find someone to even work on it here in Southeast Massachusetts. John Link to comment Share on other sites More sharing options...
