Yes indeed that blue one is like the ones I have seen. Are these (blue) a good choice for a 3 liter swap with the above mentioned recipe? Reason I am asking is due to the fact my buddy and I built his 3 liter last winter and the damn thing idles so rough it seems as the though the wheel is going to shake out of your hands? Almost like the car is running extremely rich. When on the throttle it smooths out but will occassionaly throw a missfire code in multiple cylinders. List- 98.5 SVT, 98 block and heads with svt cams,svt lower and upper intake manifolds, svt throttle body, svt tps, superchip or diablo chip with three stages,1.)nitrous 2.)burn for 24lb injectors and mass air 3.)off ,pro-flow 75mm maf 24lb calibrated, fidanza flywheel, grizzly clutch, gutted precats with Mil eliminators, off/road y-pipe, stock cat-back, we do have a apexi afc but it is to fine of a tuner for the problem we are having.
