| yep had the same problem with mine - as the others say get the jhp chip and either get them to set up the exhaust gas/fuel/air mix or take it to someone you can trust. once set up it should run smooth, shouldn't really be a big flat spot if its right and if their real good the stalling can be eliminated but as guido says its a race engine and doesn't really want to idle at 1k rpm |
