I’ve had the crank and cam sensor replaced. rough idle, no tachometer and hiccup like shifting air flow problem. not sure what else to try.

Hello,
This could be a problem with G #103 in the left front of your vehicle's engine compartment under the left headlight. Please check this ground ensuring that it is clean, corrosion free, tight, and making good metal to metal contact. I have included location information for this ground in the diagrams down below for you as well. Please get back to us with what you are able to find out.
Thanks,
Alex
