Hello, I'm new here and I've recently installed a set of Ebay headers on my '00 Boxster S. After just a couple of kilometers (I'm from holland and we use the metric system
) the CEL went on...
So I got some CELfix pipes that I placed between the rear O2 sensors and the header. These take the sensor out of the exhaust flow and the CEL stayed off
BUT with the CELfix things there's a new problem; when I drive the car and take it above 5500 RPM there's a huge cloud of smoke (I'm pretty sure it's fuel) out of the exhaust. When I let the rev's down the smoke is gone again. I can drive the car at WOT up to 5000 RPM with no problem, but when i get to the highet RPM's the smoke returns...
The weird thing is that the CEL doesn't light up, not even when the smoke starts..
It looks like the thing mentioned above (about the fuel dump to check the catalytic converters) but that's only on 2003 and up cars, and mine is 2000
Does anyone know if the headers are to blame for the smoke??
The engine is all stock and in mint condition and has only 72.000km on it (about 45.000 miles), recently replaced the AOS but that was more a preventive measure.
