It could be the MAF and O2 sensor. Better get the codes read and replace the part necessary.

SOURCE: 2003 Silverado rough idle, idles good after "check engine" light

Check your o2 sensor voltage, those trucks are real bad for o2 sensors, and yes if one sensor is reading 0mv, the others will start to drop out, and the vehicle will run very, rough. You also may check fuel system pressure, should be almost 60p.s.i. If its alot lower, Id be looking into a fuel pump. If that vehicle is drive-by-wire (no throttle cable), the throttle bodies get very dirty and cause that concern also. Id start by having the vehicle scantested.

Get the codes checked.This will tell you what cylinder is causing the problem.If the wires and plugs didn`t help then you probably have a bad coil.Hope this helps.Good luck.

SOURCE: 2005 chevy cobalt 2.2 is running rough (putting)

Number three cylinder is miss fire,it does not mean it is the coil,although it could be,remove the coil,and boot,and spark plug,inspect them to see if the plug,or boot look bad,replace the spark plug,and if the boot is burned or distorted,replace it,a fuel injector can cause a miss fire also,but change the spark plug and see if this solves the problem,if not replace the coil,if it is a dead miss,then the coil might be bad,as for the water in the fuel ,the cap is missing,,and 5 dollars worth of HEET will not hurt,also,fuel from the fuel station,can have water in it.It happens a lot.

I have a Kia Rio 2005 Cinco( 5 door) Running really rough until I push down gas pedal,,, Then it seems lOk still a little r bogged down', It doesn't stall just runs rough without accelerration? Oxyg


To begin with, is your "check engine (CE)" light on? If it was on and now its not, you need to replace the bulb. If CE lights is on, find out the codes before doing anything. If bulb is good and "CE" does not come on, begin with: (1) gapping spark plugs, (2) replace spark plug wires (if haven't changed them within the last 2), then the coil. If your Cinco is still idles rough, adjust gas pedal until idling smoothly. If this still doesn't help, replace your two oxygen sensors. If still running rough, the converter. After doing all this and problem is still present, take it to a mechanic you trust.

  • does the engine miss? bumps is a rythmic pattern?
  • an engine miss will appear to diminish at higher rpm due to centrifical force.
  • other possible problem broken or flat motor mount.
  • is the idle rough in reverse?
  • if not
  • open hood
  • start engine
  • Left foot on brake (hard)
  • start engine
  • watch engine as you select drive
  • still holding brake with left foot / throttle gas with right foot
  • does engine dramatically move?
  • if so replace motor mount on offending side
  • if not possible engine miss or transmission problems
