    The PC0101 code is for the MAF sensor. Make sure it's properly plugged in and the wiring is good. If it's all good electrically, replace the MAF sensor with an AC-Delco unit. The PC0135 code is for the oxygen sensor in the exhaust manifold for the rear cylinder bank. Replace that O2 sensor with an AC-Delco unit and you will solve that problem. PC0603 is nothing to worry about, so you can ignore that one. The PC1108 means "P1108 - BARO to MAP Sensor Comparison Too High" and I have no idea what that means so hopefully someone else will chime in with an answer for you on that one. The PC1406 code means "P1406 - EGR Valve Pintle Position Circuit" so the EGR valve probably needs to be cleaned or replaced to solve that one. PC1599 means "P1599 - Engine Stall or Near Stall Detected" so that shows the engine died previously. If you solve the other codes, the 1599 won't come back. Sounds like you have some maintenance work to do on the car. How long has the Service Engine Soon light been on, or did it eventually burn out?

    The MAF sensor is the Mass Air Flow sensor. It heats up a wire to a specific temperature and the air moving into the engine cools the wire down. The computer measures how much power it takes to keep the wire at the right temperature, and that helps it determine how much air is actually moving into the engine so it can pick the right fuel delivery rate. If it's not working properly, the computer has to make some guesses about how much fuel to deliver, and strange running problems can result.

    If you look at the air filter box and the hose that goes into the intake, that air hose connects to the MAF. It's a black plastic tube connected to the throttle body with 3 small bolts. Remove the air hose from it by loosening the screw on the clamp and pulling on the hose. Once that's off, you'll see the screen to straighten out the air flow through the MAF. Disconnect the wire that plugs into the sensor, remove the three bolts, and pull it up and out. A replacement MAF is kind of expensive, $198 at www.rockauto.com, and you'll get $66 of that back when you send your old one back to them. It's AC-Delco part number 2131616 for your car. Check the wiring and the connector to the MAF before replacing it. Make sure your air filter is good. AC-Delco air filters are darn good, as are most of the aftermarket filters. K&N and other oiled filters could ruin the MAF by coating the thing with oil.

    You'll have to depressurize the line, remove the hold downs, disconnect the fuel rail at the supply line and lift the entire fuel rail with injectors attatched.
