Don't disconnect the battery as that starts it all over again. Starting on page 10 of the attached link is what you want to pay attention to. You have to go through different types of driving and this explains the necessary driving patterns to get the OBDII readiness test to pass first. This only helps if you're failing the readiness test. If you have DTC's (Diagnostic Trouble Codes) stored, you need to get them cleared. Many local autoparts stores, such as Oreilly and Autozone carry a scanning tool that can serve to reset the DTC's. Pay attention to see if they're current. If they are, try resetting them, but they'll probably come back. If they do, look into each code. They're often interrelated.
Here's the link for the OBDII readiness. Again, start on page 9.

SOURCE: 97 grand prix gtp starts then immediatly dies

If you have a GTP these engines use a hi output fuel pump. they use a fuel pump resistor located under the battery tray (look up from under the car) This resistor lowers the voltage to the fuel fump when not in boost mode. because of its locatoin it is prone to corrosion. if you bypass the wires and the engine starts and stays running replace the resistor

i have the sameproblem. Dealer part was quoted to me at $510.00. All after market parts stores were $350- 450. Try moving the emerg. flasher button while you step on the brakes and someone else watches the lights. I jammed paper beside the button and they work until I can fix it.I had to order the multi-function switch. and you have to pull the air bags to replace it.

SOURCE: 1997 grand prix gtp. Tire pressure/abs light

Hello! This indicates a fault with the wheel speed sensor/ABS sensor. Any major auto parts retailer can pull the details of this code (which sensor) for free, which will help you identify if the wiring is loose or damaged or if the sensor will need to be replaced. If you need to replace the sensor - you will need to replace the entire wheel bearing assembly, as the sensor is internal.

SOURCE: 97 pont grand prix code po305 and engine miss fire

Hello fosch: My name is Roger and I will help you. The code p0305 is a cylinder specific misfire code. The cylinder is #5. This could be a bad plug,bad wire a problem in the cylinder or a bad injector. If the motor has the original plus and wires that would be a good place to start. Be sure to use quality parts. Easier to do the job once instead of twice. I would do a compression test on #5 cylinder while the plug is out. Any compression that is less then 100 psi. the cylinder will not fire. Should the compression be any less you will need to find the mechanical problem and repair it before you will fix the misfire problem. Should you need further help please just ask. I will be glad to assist you. Please rate the answer. This way i know it was helpful. Thank You for using Fix Ya. Roger

How can you tell if your plugs are misfiring

The computer usually picks up a miss fire way before you will notice it. If your check engine light is telling you that you have a cylinder miss fire then there could be several reasons, but starting with the plugs is as good a place as any. Remove them from the engine and see if they are worn away. The electrode can get worn and the gap get too large for the spark to jump consistently. Or it could be a bad plug wire, or if your vehicle is coil fired, possible a bad coil. It might not be in the ignition at all, might be a bad injector.

engine miss caused by many things,weak ignition from bad ignition coil, ignition timing off if you have high mileage engine low compression from worn burned valves.could have something minor like stopped up air filter, clogged dirty fuel injectors, through the years i have seen many things cause engine to miss.

Low end miss fire and no horsepower

If it really is a miss-fire, you should have a check engine light on and codes for the cylinders.
I would check for that and check the fuel pressure.
You did replace the fuel filter with the pump, right ?

Replaced the MAF sensor - nothing. Took it to a authorized toyota shop & checked compression which check out good and put the computer on. Computer read mis-fire on cylinder 1, and then multiple misfire (like it would jump around). We went ahead and replaced the fuel injector on cylnder 1 - did not solve problem as when we hook the computer up, misfire seemed tp stay at idle and seem better when running high RMP, but check engine light is on as it never went away. Went ahead and replaced the coil pack to cylinder 1 - nothing. what am i missing?

1999-E350-V10-super duty-misfires/no codes /no check engine light

sounds like you have a dead ignition coil very common problem. to check the ignition coil and fuel injector harness without a scan tool you can use a noid light. it is a 12volt light bulb that connects to the harness side and flashes indicating that the computer is firing the injector and or coil. there is no specifications to check the ignition coils the best way is with a scan tool see witch cylinders have the most counts in the misfire history your local dealer may also be able to perform a cylinder balance test to find the dead hole. unfoutunatly you have to remove the doghouse to access the rear coils and fuel injectors.

My 2000 cadillac catera check engine light is on and the tc light is on and it idle's low

What have you done so far. I would start with looking at the cars repair/maintenance history. Have the codes read (might be helpful). Could be anything, depending in what direction you need to go you might want to check for cyl. miss-fires, bad coil, IAC, fuel pressure, clogged CAT. CMP sensor. Let me know if I can help anymore.
