My car has stumbled and run strange since I bought it. It acts like a afm problem so I pulled the afm to clean and check it. I looked up the bosch number and it says it's for a 85.5 to 88. The bosch number is 0 280 202 064. Before I spend alot of time working on the afm I would like to be sure it's the correct one for my car. Is the afm for a 89 2.7 the same as the late 2.5 or is it unique to the 2.7 thanks for your help.
