Please help! 2009 Volkswagen Tiguan 2.0 T - It has a slight rough idle and hesitation when in motion esp. around 1500 - 2000 rpm. I got the code P0302 and I changed the plugs and the Cyl # 2 coil. Still seeing the CEL and the problem persists. Any clues please? -Daniel
check for intake leaks first, if none are found the problem might be a clogged injector or a bad injector or wiring to the injector or ignition coil
you can check the resistance on the injector and compare it to another cylinder
also the wiring to the ignition coil will need to be checked.
