Question about 2004 Dodge Neon

1 Answer

2004 Neon Weak Spark on #1 Cyl.

My Dodge Neon has been running rough and the check engine light comes on occasionally and then goes off on its own. I had a diagnostic run on it and the mechanic found that there was a misfire in cylinder #1. The injectors, and plug wire checked good but he found that the spark on cylinder #1 was weak (less than half of the intensity of the other three). The other three were strong and looked good. He suggested to replace the ignition coil, which i did but it did not help. What else would be causing this weak spark condition.

    Yes, the wires were swapped and it was still getting a weak spark on Cylinder 1 using the same plug to test all cylinders.

Did you try swapping plugs & wire with another good cylinder. Maybe bad plug or wire, even though check says wire good.

Not running rough slight miss at idle

check plug gap .try a little hotter fire plug. sometimes the seals around the valve cover will let oil in around the spark plug causing it to misfire. as the 4 cyl engine has a coil pack and you cant see it till you remove it.

2005 pt cruiser rough idle when ac on

The ac compressor pulls a good number of horses from a 4 cyl engine.
Any minor performance problem is amplified when the ac is running.
You probably have a weak spark plug or wire, or an issue with an injector.
Is the check engine light coming on when it is rough ?

I am having issues with my 2004 dodge neon missing at idle spped and low rpm. Is there a simple solution to look for. No check engine lights are coming on so I am unable to check any codes.

Be careful, when its running, slowly pull each spark plug wire up, if you see sparking coming out of the side of the spark plug boot, replace the wires and spark plugs. Use the correct Champion Spark Plugs.

Check Engine Light Keeps Coming on

I would almost guarantee it is your O2 sensor. You can confirm this by going to autozone and they will run a free diagnostic for you.

Weak Spark on #1 Cylinder

I'm getting real suspicious of EGR valve fault. For now, pull vacuum line off valve, and see if there is vacuum at idle, plus see if engine straightens out, when line off, idle wise.
