wall street Posted January 23, 2006 Share Posted January 23, 2006 Hi I am currently running a 90 with an auto box and 3.9 efi engine from a disco. I changed the resistor (thanks RPI) about 12mths ago and the engine ran well however the engine running has recently become very lumpy. I have cleaned the dizzy and cleaned the HT leads (magnecor) and checked that they run as separately as possibly inc king lead, I have also changed the plugs. Judging by the smell of petrol and state of the plugs (black) I am guessing that the engine is running very rich. This presumably would contribute to the lumpy running. How do you stop the engine from running so rich? And is there anything else I should be checking re the lumpy running. Thanks in advance.
