Message I know this symtom has been covered many times, I've searched and madesome repairs but nothing has improved. To start I bought the vehicle with a miss (got a good deal on it). I went through the 6ps, performed some diagnosis, ohm injectors, check timing, boost leak test,compression test. I found a couple of hoses cracked and replaced, also found two bad injectors and replaced all six. I do not have any problems while driving everything seems to be in line, it boosts fine no hesitation etc. The only problems I found were the injectors and hoses compression was fine all six were between 155-165 psi. Those repairs took care of the miss and the car barley even being able to accelerate, but now at idle I have this ever so slight miss, rpms dont noticably change and idle feels smooth except you can feel this little shutter in series of two or three every 15-25 sec. Thanks for any ides in advance.
