E30 M3 Convertible
Can someone advice a solution to resolve a failure on Carbon Monoxide & Hydrocarbon emissions, i have been adviced to replace the lambda sensor, how many lambda sensors are there 1-2 ?. The vehicle hasnt got the start it used to have, its missing, drives well whens it warm...1st & 2nd gear hasnt got that pick...3th is ok 4th & 5th is sluggish,
morning drive has popping sound each time i drop down a gear.
