I have had my 1998 Buic riviera series II for 3 months now.Two codes have been noticed. P102 AND P300.
When I drive the car it hestitates,shutters, and someTime stalls.

I recently too it to a shop ,but they never figured out the problem.I now noticed that my catalaytic ocnverter has gone bad.When I accelerate the car does go as fast.It seems as if it has an exhuast leak.

PO 102 is the mass air flow sensor voltage low. PO 300 is multiple cylinder misfire. If you drive the car with a misfiring engine, raw fuel enters the catalytic converter, overheats it, and causes it to fail.

Start by checking the MAF.

Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires.
Inspect for any air leaks near the MAF sensor.
Take the MAF out and clean it using a spray cleaner like electrical contact cleaner. Be gentle with the sensor.
Check the voltage of the MAF sensor (refer to the FSM)
Replace the MAF sensor.

did you replace the air filter with a K&N by any chance?

Hello Heartbeat here... I am going thru some things i have 96 rivi with Series 3 under the hood.... So the other day i changed my oil and a few lights came on ses antilock trac control and they stayed on.... With this i didnt know switching to full synth would make all this go in to play so.... I took it to the auto parts store and tested it it thru me back mass air flow too low, shift solenoid 1&2 but with all this happening the car would not take off or do any of my regular day driving as it would

Your change to synthetic oil has nothing to do with your lights.
