karmannG60 0 Posted June 2, 2003 my corrado is using alot of fuel these days i used 55 liters on 198 miles (320 Km) Took out the spark plugs yesterday to find them covered in black dust, and the exhaust is slightly blackish. Done nothing to it lately, so i guess there is some sensor somewhere that may be defect, has anyone got an idea on what might cause this problem? abit expencive driving this car at the moment.... -Chris Quote Share this post Link to post Share on other sites
G60Jet 1 Posted June 2, 2003 Your running well rich? my guess would be a vacume hose split, you know the 1m one that runs to the ECU Quote Share this post Link to post Share on other sites

steveo29 0 Posted June 2, 2003 check the c/o pot ohms.....theyre best around 450-500 ....higher ohms =less fuel....maybe the blue temp sender Quote Share this post Link to post Share on other sites
