2007 Versa, just hit 200,000 miles, major tune up, changed valve cover gasket, spark plugs, ignition coil, O2 sensor, EVPR valve, PCV valve, now one problem left I cannot fix the problem. Cold start, the RPM go from 1300 down to 900 no issue. As long as I shifted to reverse or drive, the RPM dropped to 800 and felt the car had rough idle (vibrating). Put back in park or neutral, it's better, climb back to 950 RPM. Drive on the road feels ok, accelerate on highway no issue. I thought it is vacuum leak, spray Carb cleaner to all hoses, no change. check MAF, looks okay, unplugged MAF and start the car, drop dead. Plug back in, car start, no issue. Plan to do compression check this weekend. Need some pointer how to fix the problem.
