rought idle at first a.m. start.. motor shakes a bit.. raise RPM and smooths right out.. driving up an incline will also cause this. Check engine light is on. not sure what sensor to even suspect. misses occionally at high speed as if a cylinder is not firing. No rich mixture smell in the car.. Is having the plugs and fuel system pressure checked. Not sure what sensor would or could be the main cause or should be checked first. Maybe a cracked vacuum line or pcv valve? Seems to be a bit smoother runnintg after warm up going 55-60 mph.. suggestions or advice welcomed.. thank you.
