I’m not a car expert by a long shot, but this one has my Mechanic confused too.
My Toyota 4Runner 1999 model has all of a sudden started misfiring when Idle. It acts like it wants to die. It also has an odd smell coming from the exhaust too. It throws error codes about cylinder misfiring.
What’s been tried:
The mechanic changes the coil pack it said had the error, but the problem remained. He checked, the MAF, spark plugs, vacuum hoses, and wires. No dice. He is confused as to what could be left as well.
When you drive down the road it runs just fine until you idle at a stop light or so. The only thing left I can find on the internet to try is the catalytic converter. They say the misfire code and the bad smell can be caused by this.
I’m told the dealer could tell me the exact problem with a diagnostic test? Is that true? Or will it still be a needle in a haystack?
Any help is greatly appreciated!
