I got the Hall Sensor connector fixed THANKS ALL...still trying to fix this recent rough idling issue - bumpy acceleration up to 45mph? It runs better at 55+. This car has always been a great ride with smooth strong acceleration.

Current Mileage: 140,400

Here's what I've done:
1. Installed new Bosch Platinum Plugs (been using 10 years with good results)
2. Replaced distributor cap and rotor. (I was told locally this was "stage coaching" and to replace the distributor cap and rotor. I did and it seems a little better.)

FYI...
>>On 11/04 & 140,000 miles, had throttle plate cleaned/adjusted after taking it in for rough idle and thinking I had a bad Constant Idle control. This corrected the problem until now. It's not surging and cutting off at idle like before. The tach needle is holding level at around 900rpms.
>>Plug wires were replaced 2 years ago with upgrades - still look new.
>>Fuel filter was replaced in 1999 at 95,000 miles.
>>Air filter last replaced ? Doesn't look bad.
>>Small diameter vacuum hoses are spongy:cooked and cracked pretty bad

Any ideas? Thanks!
