Help! I've gone from bad to worse. My '89 740 (B230FT) was bucking slightly on acceleration. I replaced the plugs and wires. Was told it is probably the distributor cap and rotor. I fairly mechanical, but while replacing, noticed something loose behind the distributor housing next to the firewall. I saw a reference in the brickboard FAQ to the Hall Switch Connector broken away from the housing, and believe that's what's happened. I see 3 black wires still connected, but the plastic bracket that fits into the distributor housing groove seems to be broken and won't stay in the slot. Now the car won't start. Can just the switch be replaced? I'm frustrated, broke, and am almost out of patience. Thanks!
