Any one ever have a problem with a 97 es300 surging at idle? A foul odor from the exhaust tipped me it was running rich. With a snap-on scanner hooked up the mass air flow sencor was reading higher voltage than at normal idle, while the 02 sencor was reading lower. first thought was an inaccorate
02 sencor but the dealer insisted they have had alot of problems with iac motors, but after I replaced it the car still acted up. The problem only happens after extened criusing. Any help would be appreciated. Ken- posted
