Have vehicle scanned to determine the problem
the 02 sencers are in the pipe, if there is a problem with them it would cause the check engine light to come on but the pipes themselves wouldn't
get the alarm code and repair the problem, as much as we dislike the light it's our friend
Black smoke means the engine consumes too much gas - possible problem with fuel injection. Is your check engine light on? It could also be a problem with oxygen sensors.
Tire pressure will not cause a check engine light.
Take it to repair.
yeah too much oil or low on oil will trigger the check engine light it happen to me on my 2000 altime gxe .
If the check engine light is on, or has been on, have the codes read, they may help lead you to the problem.
If your check engine light is flashing that means an engine cylinder (s) misfire has been detected what is a engine cylinder misfire and how much bdoes it cost to fix it
As far as I know the check " gage " light comes on if your engine temperature is too high , your oil pressure is too low , or your gas gauge is at or near empty , so it would depend on what is causing the light to come on
First you need to repair the problem or the light will just come back on. The charge varies greatly from place to place. Try disconnecting the battery for 1 hour which works on some vehicles.
On my 98 Cirrus, replaced the fuel cap and then disconnected the battery for 10 minutes and the check engine light turned off. My wifes Lexus had a similar problem. Sometimes a different brand of Gas will do the trick too. ^ I tried this today and it worked! Thanks so much =)
To much oil in an engine can cause it to flood which will then lead to blowing seals. But it should not effect how the car idles.
