i cant find the idle adjustement screw on my 89 740 GL (B230F engine, 2.3L) with LH-jetronic system. does it even exist on that engine? its not under the throttle body...
also....
its running very rich. how can this be adjusted?
basically i have a bad idle and poor acceleration.
i have checked/replaced:
-AMM
-TPS
-Air control valve
-fuel pumps/filter
-o2 sensor
-cleaned throttle body
-cleaned out intake with seafoam
-spark plugs/wires
* i think that it could be the temp sensor or the fuel pressure regulator.....what do you think?
any help/suggestions/comments are greatly appreciated!
thanks in advance!
