Does a 1990 740GL have an air mass meter? I've looked all around the intake manifold, air box, throttle body - I don't see anything like my manual depicts. I noticed that the partsamillion web site only shows the AMM for 740 8-valve cars through 1988. Did the 1990 version not use an AMM? If so, where in the heck is it located?
Does anyone have the cold start injector wiring pinouts? If they both connect to the ECU, what pins in the ECU harness? Can I static test at at injector pins for resistance? Should it be the same as the other injectors (~14 ohms)? Is there any other way to test it while mounted - I did see the post about removing it, putting it in a jar and turn the engine over without starting to test for leakage. The diagnostic connector is still logging a 3-2-1 code, no signal or signal wire grounded to CSI.
