check all the tune up basics first. Check all the vacuum lines. Clean the throttle plate, clean the aic valve shutter wheel, set the base idle and throttle swich. Check the ignition timing, on a 87 9000S it should be 14 degrees BTDC. If all this fails to resolve the problem, and your air mass meter ends with 005 in the Bosch number, it is a common problem that a new meter will take care of.
