I just had some mods done inc sbtb and a new tune. Having a stalling problem. only when pushing in the clutch at 2400 rpms or so and letting off the gas to coast to a stop. The motor falls on it face and dies. If I do the same thing at a lower rpm it is fine or down shift to a stop its also fine. I have cleaned out the iac and set tps sensor to .98 volt. The sbtb has a slight sticky spots at idle not sure if that could have something to do with it or the iac is bad or possibly the tune just needs a little tweek. Any body ever run into this problem?. Thanks sean
