Exhaust sputter problem... NEED HELP!

Re: Exhaust sputter problem... NEED HELP!

Alright, thanks I'll try to get under the hood here in a day or two and see what I can figure out.

Re: Exhaust sputter problem... NEED HELP!

now remember. You need to have the codes ran first. (have them deleted) then drive or attempt to drive and if you cant. Just turn the car on and off about 5 times, and press the gas pedal from idle to mid to wide open throttle a few times. that should tell the computer if the sensor is bad or not. ( i know mine was.)

Re: Exhaust sputter problem... NEED HELP!

So if the sensor is bad it should trigger an SES light when I rev it up after the on/off routine?

Re: Exhaust sputter problem... NEED HELP!

yes. most definitly. Because it effects engine stability in regards to (ignition,revolutions per min.,and air mixture with gas.)

Re: Exhaust sputter problem... NEED HELP!

these tps sensors tipically cause problems in the rpm range your talking about. (it did for mine.) "both times when it went out"

Re: Exhaust sputter problem... NEED HELP!

Ok, once I get a chance I'll go get the code deleted and try that out and see what happens

Re: Exhaust sputter problem... NEED HELP!

alright. hope everything works out man. good luck.

Thanks I'll update when I have a better grasp on the problem

Well were both plugs on the coil pack misfiring or only 3? I was told if the coil pack fails both terminals fail?

no just the one. I replaced the plugs and it didnt change anything. I then replaced the coil pack and it solved the problem.

Re: Exhaust sputter problem... NEED HELP!

is there any way to check the coil pack or just change it and see what happens?

Re: Exhaust sputter problem... NEED HELP!

here is what i got from yahoo answers about checking the coil pack.


"to check the coilpack ..just get a test light ground it some where on the block then press the the test light on the head of each wire at the coilpack.. you should hear a change in the way the car idles..if you get to one of the wires and the idle does not change.. that is the cylinder that is giving you the problem.but it could be dead cylinder and not the coil pack"


this is from ehow

A faulty coil may fire intermittently, produce a weak spark or kill a cylinder completely. Coils are very sensitive to heat, and may produce an intermittent problem if their internal components become sufficiently weak over time. Once the winding inside weakens or brakes, the problem is irreversible. However, you can test the coil pack on your car using a voltmeter to see if they need replacement.

Step 1Park your car in a safe place and open the hood.

Step 2Locate the coil pack in your engine by following the spark plug wires from the spark plugs. The wires are connected to the coil pack. Depending on your particular vehicle model, you may find the coil pack mounted on one side or the back of the engine.

Step 3Unplug the spark plug wires from the coil and label the wires if necessary for proper installation; then, unplug the pack electrical connector.

Step 4Remove the coil pack from the engine, if necessary using a wrench or ratchet and socket. If your coil pack is mounted on the back of the engine, raise the front of the vehicle and safely support it on two jack stands to reach the coil pack from underneath the engine. Remove the coil pack.

Step 5Check the secondary resistance on each coil. There may be two or more coils in your coil pack assembly depending on the number of cylinders on your vehicle. Each coil fires two cylinders. Set your ohmmeter to the 20000 ohms range. Turn on your meter and touch the spark plug wire terminals on one of the coils with the meter leads. You may get a reading between 5000 to 15000 ohms, depending on your particular model.

Step 6Check the primary resistance on each coil. Set your ohmmeter to the 10 ohms range. Touch the terminal B+ (usually the center prong on the coil pack electrical connector) with one of the meter test leads, and touch the corresponding coil prong on the electrical connector with the other test lead. You may get a reading between 0.3 and 1.0 or more, depending on your particular model.

Step 7Repeat steps 6 and 7 for each coil in the pack assembly, and compare your resistance readings to the specifications given on your vehicle service manual. (See "Tips," below, for more information.) If your readings are out of specification, replace the coil or coils as necessary.

well if i come up with nothing on my initial search that'll be the next thing i try

Re: Exhaust sputter problem... NEED HELP!

to see if your coil pack is bad just swap it to another set of plugs. if the miss moves then the pack is bad. if it doesn't then the wire or plug is to blame.

Re: Exhaust sputter problem... NEED HELP!

*Update: took my car to our family mechanic and he did a whole slew of tests and it turns out my ignition coil was bad. he swapped it out for a new one and in a couple hours i'll be able to go check it out and see how the car runs now. i'll keep you posted.

Hope it works. Why the long wait?
