engine code p0300 misfire
Hi great site with a lot of information,
I need help with my 99 boxster 2.7 with 65000 miles the engine light is on with 4 fault codes
p0300, p0301, p0302, p0303 misfire the car will barely rev up and driving it along it is hard to get above 30 mph,
there is a strong smell of unburnt fuel b ut it does not sound like its misfiring just the odd pop and bang not a constant misfire i tried cleaning the airflow sensor and reseting the engine light but it is still the same
has anyone come across anything similar ???
regards Dave
