Hello everyone! I did a search in regards this code P050B and couldn't find no information on how to fix it. I was wondering if anyone had this code come up and how you fix it.

Problem》 The car loses performance and the motor makes these sudden jolts like it would misfire. Is very bad at times that even at idle it will do it.
Need help on how to identify and fix the issue.

Thank You in advance I appreciate it.

 

Start by looking for vacuum leaks, listening for air flow, remove and inspect air filter, clean the charcoal mesh filter and MAF sensor using only MAF sensor cleaner. You might also pull the TB and clean it so it seals properly.

When done, disconnect the battery and let it relearn and see what happens. It will idle high and make some strange noises for 5min.

Report back.

 

Thank you for this information, I do apologize for such a late, late response. I totally forgot I had placed a thread on this.
BTW, Happy New Year!!!

update; replaced spark plugs and took car to dealership and had them clear the code. It was the spark plugs, misfire on cylinder 3.

Thank You again.

 

I have the same issue .The fix is to buy Veepeak from amazon download the OBD fusion app. for your phone Bluetooth. plug in the veepeak. turn ignition to on . On your app connect and clear code. There are many other codes that this product will do. Simple and about $22.00.
