Just wondering if anyone could help out... The first issue is that when the car is sitting it pulsates.. meaning it fluctuates through the rpms.. it sounds like i might die out then revs itself up a little but then falls down again.... The second issue which I am not sure if it is normal on these cars or not is that when starting the car it takes a couple of seconds of cranking to finally kick over.. not sure if that is how they all start or if i need to update some parts. Thanks By the way I have a 1987 Camaro Iroc w/ 350.
