That is exactly what my car does! I changed the spark plugs b/c my husband said it could possibly be that but It still does it.

 

It could be your catalytic converter. If your plugs were fouled badly then unburned fuel could have caused damage to your catalytic converter by super heating it. This may be causing the bad smell that you are now noticing.

It could also be a bad O2 sensor. Super heating the exhaust could also damage this and cause it to send bad data to your ECU.

Have you checked for DTCs or is your CEL on?

 

My check engine lights not on But now that you mention it whenever i go on a long trip in the car the check engine light always does come on but then it will shut off in about a day or so.

Also, I might sound dumb for not knowing this but what is DTC's??

Thanks for the help.

 

Diagnostic Trouble Codes (DTC) are stored to tell a technician what is wrong with the car. If your CEL goes on, a DTC should be stored indicating what the problem is. Even if the CEL goes off, the DTCs are stored. You can use a scan tool to tell you which DTCs have been stored. They're available at Autozone and other parts stores.

 

Oh Alright, Thank you!
