      Check for proper fuel pressure, check spark at the spark plugs. Check for a clogged exhaust. Check for applicable trouble codes. To check codes yourself, at the least, you need an obd2 code reader.

      Yes, the starter motors are the same part for the 3.1L engines - both the 2000 and 2002 model years.

      The parts are readily available from these many on-line sources, www.partsgeek.com, www.rockauto.com, www.discountautoparts.com, www.autopartswarehouse.com, www.jcwhitney.com - to list only a few possibilities.
      In fact, they (RockAuto) list the starter motor from around $65.00 for your vehicle - there are several brands, such as; TYC part # 106481, REMY part # 96221 or similar / equivalent.

      I can tell you that acdelco starter part #, 336-1921, vin J should work, 00--03. I can't be sure about any other part #.

      Obtain a Digital Voltmeter and measure the readings, if it is hot then it shows 12 volts and if it is low then the voltage reads less than 12 volts.

      Possible solutions.

      Clean the MAF sensor. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or MAF cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling

      Inspect all hoses and connections in the air intake system Inspect and/or test the intake manifold gaskets for leakage

      Check for a dirty fuel filter and proper fuel pressure

      Ideally you'll want to monitor short and long term fuel trims using an advanced scan tool

      If you have access, you may want to run a smoke test

    Why is my car so loud!?
    Recently bought a 94 pontiac sunbird. It rubs great, no CEL, nothing at all except for how loud the car is. It's loud at idle, but the sound lightens up under acceleration. At first I thought it was exhaust, but I would think that acceleration would make it ...

    Im looking for a vaccum line that goes from the pedal to under the hood
    when the brake is applied it sounds like it is hissing under the dash

      Check the brake booster, under the hood. If you think the brake pedal arm is hitting a vacuum line, watch the arm when you activate the brake pedal, see if it is hitting anything?

      First make sure you have belt tension. Second Make sure all your connections are tight and clean on battery alternator and starter.

      Sounds like a bad voltage regulator. You probably got a bad alternator from the parts store. That happens quite often especially if it was remanufactured. Or you could have arced it while installing it. If you changed it without disconnecting the battery you will fry the new alternator. Or if the positive cable on the back of the alternator touches the alt. housing it can also arc and fry the regulator. The voltage regulator is sensitive to heat. That would explain why it works for a short time. Once the car warms up it fails.

      It could also have high resistance in the alternator wires. Likely the battery power cable to the alternator. Check the connections at both ends for corrosion.

      I would guess that you got a bad part. Check your part warranty and take it back. Install another new alternator.
