Check the firing order.
It sounds like you have crossed a couple of wires.

2004 pt cruiser turbo idling and running roughly


c99fd777-e303-4157-9a0b-18509a067e72.gif you would need to do a running test. but if its worse with new injector. then it can be the dispack fault. it feeds the spark plugs. have seen some were the unit has leaked. and made like a cement on the shaft that is the inside of it come out and dropped down the shaft. also the rubber will go white like water marks. check them to make sure they are the same if it does look like what ive said change it. they are not dear to replace.

Sputtering misfiring


It wouldn't hurt to change the plugs. I never run plugs over 20k in my cars. Also, I've said this a lot in answering similar questions here, but check the O2 sensor, if it's clogged the vehicle can run rough especially when its idling and can go away when the RPM's climb

Try swapping the injector on that cylinder with the one next to it and see if the misfire changes to the other cylinder.If it does then you have a plugged or bad injector.It it still stays on that same cylinder then check compression on the number 6 cylinder.Let me know what you find out.Good luck.

Idles rough. when under load, it sputters like a cylinder is misfiring. no smoke or leaks. any idea?


well. if it idles rough without a load and then worse with a load i would try changing spark plugs and ign. wires. also try pulling out your idle air control valve and clean it out. if that doesnt work look up testing for your throttle position sensor. check for worn vacuum lines and check for vacuum leaks. if it runs rough throughout driving it will be ign. or fuel delivery. get some injector cleaner and throw it in your tank. if non of this works then your in the same spot as me bud. oh and check your camshaft position and crankshaft position sensor and also your speed sensor.
good luck to ya bra

I have changed plugs using the platinum plugs and the problem don't go away. These plugs can make a car run worse in some cases. I have found it best to use the OEM or a step above on 4 cylin and 6 cylin engines. The Plats work fine in 8 cylin engines. You could also have a bad plug wire. The plug wire could be jumping spark. At night, open the hood, start the car with lights off. Look around the plug wires for sparks jumping. If a wire is bad, the spark is leaving the wire and grounding itself to the nearest metal causing rough engine idle and misfire.

Rough idle, sputtering like its outta gas but it aint.


Could be a vacuum leak as it falls off under acceleration and does not play a part then. Check for broken or cracked hoses.....

Buick Century 97 runs rough and stutters when cold and gas applie


Your cat should last quite a while now it is replaced. I recommend testing coil packs and module. Change plugs and wires and double check your vacuum hoses.

ford has a technical service bullitin out on this vehicle for the intake gaskets leaking causing a vacum leak that set codes 171 174. the solution is to have the intake manifold gaskets replaced . call your local ford dealer and see what thay can tell you about this bullitin.

Erratic idle and misfiring problem


when you changed the valve cover did you bump the distributor a bit? If it has a distributor mounted on the head you can loosen it and turn it to advance the timing. it may solve your problem.
