The Torque Meister
Saab/gm/vauxhal diesel 2.2
OK, clean air is sucked in through the air filter, through the MAF Sensor, through the intercooler,through the turbo past the MAP Sensor through the EGR Valve into the cylinder, Yep a one way street, So why is my MAP Sensor getting clogged up with carbon so much, (It's making my engine run so rich as it cant read the pressure) It seems the exhaust fumes are coming in through the EGR valve the wrong way which seems impossible considdering the pressure the turbo generates.
The codes being thrown up say egr fault but it works by remote, All signs are that the EGR is working , ( I have cleaned it many times also the manifold and now the map sensor needs to be cleaned every 12 miles or the car runs rich and smokes like crazy, A never ending circle, (The MAF checks out as working as well)
I have tried 2 mechanics, read loads on the internet and god knows how many fault readers and still the problem continues,,,,,,,,,,,HELP
