I have a 2003 Neon SXT. It does not have a distributor cap. Sparkplug wires are to be change at about 45,000 miles as they build up current resistance with use.

As Guru stated change your air filter. It may be so dirty that not enough air is getting in for complete combustion. Hope you can solve your problem.

Rough idle


This could be the O2 sensor or the MAF sensor. Try disconnecting the MAF sensor and if the idling seems normal, the MAF sensor is bad. Yet, it is always better to get the codes read if the CEL in blinking.

Really rough engine idle at cold start up,, reving the engine seems to smooth it out,,,,


Some causes about rought idle could be:
- Valve adjustment
- Incorrect ignition timing,
- Vacuum leaks
- Bad ignition wires (Test w/ ohmmeter)
- Incorrect idle speed
- Cold Start Injector always "ON" (Revised injector time switch avail.)

A source of rough idle in EFI engines is air leaks or vacum leaks these leaks will upset the fuel mixture without triggering any codes. A bad oxigen sensor will also cause a rough idle, but you should see a code for it ( I think is number 5, but check it).

A good place to start would be an inspection of the spark plugs, plug wires, ignition timing, and idle speed. Next would be valve adjustment. Don't overlook the simple things.

Hope this helps, keep us updated and just keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa.

Started in cold weather yesterday. Ran real rough, almost like a motor mount bad. Fan turns by itself when turned with your hand.


If it only happens in cold weather, check your intake manifold bolts for tightness. #5 & #6 by the firewall are easiest to check. Some people will find these not even hand tight = rough running car.

However, if (when cold) your car is vibrating at idle IN GEAR and stopped, this would be a motor mount on Envoys and Trailblazer, very common.


Fan shouldn't turn by itself, you may have a bad fan clutch.

COLD START ROUGH IDLE


I hate to be the barer of bad news, but may be the head gasket.

My car started with rough idle. Then very hard to start in cold weather. Next started overheating, but no output from heater. Trickling sound from behind dash board. Overflow bottle overflowing.......

I replaced the water pump, radiator cap, thermostat, coolant, fan belts, power flushed the system. Nothing worked. Some research gave me the answer.

The head gasket leak was allowing exhaust gases to enter the cooling system, displacing the coolant. After use, as engine cools, coolant is sucked back into the system and coolant seeps into the cylinder. This gets worse over time.

First thing you'll notice is the rough idle as the spark plug burns off the coolant in the cylinder. (This is especially true at low temperatures.) If it is the head gasket, the other symptoms will follow as time goes by.
