Question about Chevrolet Aveo

1 Answer

Hi Guri Dave :) I changed the spark plugs on my 2006 Aveo and found oil in 3 out of 4. It also hesitates and idles rough. Worse when hot, or AC is on. Also, sometimes the RPMs float and seems to have a hard time changing gears. Is this a valve problem....? timing belt...? Thanks!

Oil on the plugs means bad valve seals or very worn piston rings. These symptoms will cause a loss of power to the engine

Am changing plugs on 2006 aveo. Found oil in the


Yeah, kind of. The valve cover gasket needs replaced. The seals around the plugs go first because of heat. If the oil mark was near the top of the plug boot, replace the valve cover gaskets/seal. If it was near the bottom, slap in the plugs and wires.

2006 Chevy Aveo Acceleration Issues??


If it was running properly before you changed the spark plugs and wires, check to be sure you have the wires routed properly from the coils to the plugs - correct wires on correct coils. It sounds like you may have a couple of wires crossed. Also, some engines are particular about the type of spark plug used. Check with your local Chevrolet dealer to see if the type plugs you used have been known to cause problems with the engine.

Hi, my1997 dakota with a 3.9 engine has a rough idle, has plenty of power i replaced plugs, wires, cap,pcv, rotor and added fuel cleaner. its a little better but still has a rough idle


My uncle worked at a dodge dealership as a head mechanic for over 30 years and he also found all of the 3.9 liter engines to have the rough idle. The rough idle cannot be explained but it can be made worse by buildup on the engine. I have a 2001 Dakota sport with the 3.9 and mine does it too and one of the first times i drove it it stalled and its not a Manuel transmission. But onc I changed the oil and put Lucas oil additive as well as regular additives to my gas every month or so it has reduced greatly and not stalled since. Hopefully you find this helpful.

2006 chevy aveo. the dipstick reads oil is full. but there is oil in the spark plug holes.did the mechanic overfill last oil change. that was 4000kms ago. dipstick still reads full oil


You have oil in the plug holes because the seals that are supposed to keep oil out are leaking-you need to remove the valve cover to replace them.

We change the spark plug of my aveo 2004, and we found out that there is a oil leak on the third cylinder, what may cause the problem?


The valve cover has rubber o-ring seals that fit into the valve cover and seal oil out of the spark plug wells. Over time, they get hard and shrink, allowing oil to enter the plug wells from the top of the engine. You need to remove the valve cover and replace the valve cover gasket and o-ring seals. The seals should come with the valve cover gasket set.

Hope this helps,
Dave

04 mazda 3s 2.3l. the emgine misfires randomly but frequently. does have power loss and poor gas mileage. there is no check engine light and had recent sparkplug change with motorcraft platnums and oil...


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.

My 2002 taurus dohc runs rough at idle, worse if i turn ac on!


The a/c makes it worse because you are asking the engine to pull a load missing one cylinder. If you have alternate transport or like working on a hot engine you can take number 3 wire to the autoparts and get one wire to match length. You may want 1 plug in case wire doesn't help.
