Kirk Posted July 1, 2008 Share Posted July 1, 2008 My lil vw polo runaround (1.4 8v) appears to be running rich BUT it doesn't actualy seem like it is, its ideling fine, no leaks, plugs are clean but yet the fuel guage is telling me different... now the only things left I can think of is A, MAP is dodgy, B The sender unit is dodgy or C the lambda sensor is faulty.... Any thoughts??? Quote Link to comment Share on other sites More sharing options...
creative Posted July 1, 2008 Share Posted July 1, 2008 doesnt a faulty lambda cause a car to run rich? i would suspect that first. Quote Link to comment Share on other sites More sharing options...
Kirk Posted July 1, 2008 Author Share Posted July 1, 2008 Well yeah that's what I thought but usualy there is other signs to tell if its running rich like the engine choking itself or fouled plugs but its all in check Quite baffled Quote Link to comment Share on other sites More sharing options...
JustGav Posted July 1, 2008 Share Posted July 1, 2008 Didn't they have adjustable airflow sensors, usually a tiny little adjuster screw... Will see if I can get a pic from a mate's golf 8v. Quote Link to comment Share on other sites More sharing options...
Kirk Posted July 1, 2008 Author Share Posted July 1, 2008 I thought air flow was measured using the manifold absoloute pressure method? But if you can get a pick that would be great help Quote Link to comment Share on other sites More sharing options...
