Starting about a week ago my car has started to randomly start missing while driving (usually under a form of acceleration). What happens is while accelerating (normal or fast) the rpm's will be rising smoothly and then randomly miss a couple times and then keep rising and maybe miss some more (never in any sort of pattern or anything like that, completly random) and then sometimes it will run perfect and not miss at all and then the next shift it could start missing again. example: revvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvmissmiss revvvvvvvvvvvvvmissmissmissrevvvvvvvvvvmissrevvvv or somthing similar to that. It will sometimes throw a code 14 but usually it will just keep on missing without any codes. It idles like usual and neutral revs like it should (without missing). Any ideas? Im stumped.

Code 14 is "No IGF signal to ECU 3 times (for turbo motor) in succession".
A lot of things can cause it...igniter, poor igniter ground, coil pack, plug wires, plugs. Anything that prevents a spark from happening...any of these will cause the miss you're describing. It has to happen 3 times in a row for the ECU to throw the code.
Do the simple things 1st...change your plugs and wires...especially if that has not been done for a while. Test the igniter and coil packs per the TRSM. Make sure the igniter is grounded against the chassis...it grounds through the case. Clean the "foots" with a wire brush and make sure the bolts are tight that secure it to the chassis. It can also be in the wiring to the ECU itself...lets hope it's not that one
