I also have the same pronlem when Im driving and i either put it in neutraul or just push in the cluth it will die on me out of no where! I was thinking the tps!! I have an in tank bbk fuel pump 255lph 347 Eagle short block, forged crank and pistions,Tfs heads 185cc, Holley systemax intake, trick flow stg 1 cam, 4.10 gears, T5 tranny, 32lb injectors, Saleen rear axle, MSD ignition Griffin aluminuim radiator, Optima battery, A/C eliminator, 70mm throttle body, king cobra cluth, BBK longtube headers and x pipe, flow master exhaust 40series mufflers egr eliminator plate.
Should I just follow the surging idle check list??

You can pull codes yourself. Do a wick search on here and you can find detailed instruction. I would follow the surging idle check

See the "Surging Idle Checklist for help with all your idle/stall problems. Everything you need to find and fix idle problems is in there.

The first two posts contain all the updates to the fixes. At last count there were 24 possible causes and fixes for surging idle/stall problems. I continue to update it as more people post fixes or ask questions.
