Cheers all! Here it is..
305TPI T5
Idle is perfect. Slowly stepping on the gas in neutral, car stumbles a lot around 1500 to 2000rpm. My Accel cap is 20,000 old along with the Taylor wires and Bosch Platinum's. How often do you guys change your plugs? My car runs a little rich (black sooty exhaust leaves a little stain on the back bumper) Can I just back up the timing a little to cure this?
This stumble is really killin' me right now.
Any help is appreciated!

Thanks

Steve,

20K is probably overdue for routine maintenance. Pull the plugs, meter the wires, inspect the cap and rotor, change filters, clean the IAC, TB, PVC, test the fuel pressure, check the timing, set the TPS, and be on your merry way.

Oh, don't forget the cooling system flush, oil, trans, differential, and wheel bearing service.
