First step, check for computer codes.

To check the computer codes:

With the engine off, switch the ignition key on-off-on-off-on, leaving it "ON". Do not go to "start", just "on" during this procedure.

Watch the "Check Engine" or "Power Loss" light. It will turn on, then go off, then will begin to flash-out any trouble codes that have been stored. For instance, if it flashes:

flash flash flash

flash flash flash flash flash flash flash flash

flash flash flash flash flash flash flash flash flash flash

Then you have a 12 (one flash followed by two) a 35 (three and five) and a

55 (five and five). 55 means "end of codes" or, if by itself, "No codes stored. Check the codes and report what you find.

If the plugs were that bad, did you do the wires, cap and rotor as well? I just bought a 91 Sundance to drive as a work car, the plugs and everything associated with them were shot. Major improvement in running after all were changed.

Have to agree. The no-power-until-about-30-mph sounds very much like the problem I was having. Replaced plugs and wires at the same time (no rotor). Problem solved.

12: Start of codes 21: Oxygen sensor reading doesn't change 41: Alternator field control circuit open or shorted 55: End of codes

The 21 means that the car will run even better (and get much better mileage) when you replace the Oxygen sensor, which is not difficult or expensive to do.

The 41 means your battery is either being undercharged or overcharged; better get this fixed pronto or you'll get stranded.

Thats incorrect info again. The first thing you need to do is fix the charging problem. If it is overcharging or undercharging the sensor values could be incorrect. With the sensor values working on 5 volts and a charging system malfunctioning, this could cause all kinds of problems including rich/lean problems. Daniel, are you having people throw parts at cars again? Thats not like you pal!!

i used to have a overheating problem with the car and it used to spray hot coolant all over the alternatior. i think thats what damaged that.

Before you throw parts at it make sure the charging system is working correctly

the charging system seems fine ive never had a problem with it.

No... you've got a code saying that you've got a problem with your charging system. That means it doesn't seem fine at the moment, no matter how little trouble you've had with it up until now. It's time to find out if it's still fine.

Yup, replace the 02 sensor, but if you ever have a charging problem, be it over or undercharging, thats the first thing you need to correct before anything else.
