DID ANYONY EVER CHECK YOUR EMMISSIONS?YOU WOULD BE AMAZED WHAT A CLOGGED CATALYTIC CONVERTER WOULD DO (MANY OF MY CUSTOMERS CAME IN WITH THAT ONE)

Check compression in number three. You could have bought a bad engine. And yes. You need to change every sensor. If they don't match with the plugs. replace the engine. There is a reason for different engine codes. You should have stuck with them.

Running rough no power


Time for a major tune-up!
Plugs, wires, coil packs, throttle body cleaning, fuel filter, oil change and filter, and clearing of ODB code issues.

With the vehicle having set for three years without having been driven, running rough or rough idle could be anything. Did you inspect the spark plug wires thoroughly to make sure there were not damaged? Did you drain the old gas and replace it with new? Are are you getting a check engine light? There are some simple steps to test the coil pack and here's an easy one

My '01 impala 3.4 v-6 flat spots when COLD, at around 20mph. the idle is ruff with random misfires. acceleration is overall poor. when HOT, most symptoms go away leaving only some slight acceleration...


depending on mileage, but possible tune-up could fix it. if already done then check ignition coil pack and ignition wires also spark plugs, check vacuum hoses for leaks or porous, last injectors clogged - use some techron fuel injector cleaner (wal-mart has them). Also get the throttle body and iac valve cleaned by throttle cleaner . Also this other possibilities are to be checked and confirmed.:---- Engine running rough or misfiring can be cause by the following:

1.Defective spark plugs
2.Inadequate spark/coil, defective spark plug wire.
3. Lack of compression
4.False air leakage.
5. Faulty fuel injectors.
6. Insufficient fuel pressure.
7. Contaminated fuel.
8. EGR valve that is leaking.
9. Oxygen sensors.
10. Throttle position sensor.
11. Manifold absolute pressure sensor
12.Mass Airflow Sensor
13.Idle air control valve

--------- This should help.Keep updated.Thanks.Helpmech.

Rough idling and accelerating after recent tune-up. Cool Pack needed say shop


Best thing to do is go to Auto Zone or Parts Source and have the computer scanned for DTC codes. 
The codes will give you a better understanding why the car is running the way it is and what parts you need to replace if any.
The cool thing is that they will scan for free and give you the how to do it your self it you decide to change the parts your self.
Good luck and hope this helps. It may not be your coil packs, it may just be bad plug wires or dirty fuel injectors.
