Recently bought a 95 E320 with 89k. Its now at 91k and I have already replaced front rotors and pads, oil level sensor, fuel line on fuel filter, and also an oil change. Is there anything in particular to look out for at 90k? Check engine light is on, checked and its diagnostic code 4 (Air injection inoperative). Before I go ahead and buy a MAF sensor how exactly do you check to see if you have any vacuum leaks? Im pretty handy, however I have never performed a vacuum leak test. Thanks guys for any help and or advice! Pics will be up this weekend once I give her a nice detail

The transmission really enjoys a refresh. Coolant and thermostat is a good idea before the summer. Brake fluid and the windshield washer fluid are good to change too..

Power steering and diff oil if you wanna go all out.

Diagnosing vacuum leaks, ummm, you got them. Replace all rubber components in the system and you'll have less of them.
