Answer Question
What’s causing code P1131 on my 99 crown victoria?
A week ago I changed my plugs because the car was misfiring on 2 and 7. After that the car has been fine until yesterday when another CEL came on. There has been no difference in the way the car is driving even with the code. It's for P1131. I was reading it could be a dirty MAF sensor but that if it was the MAF it would affect both sides but that's the only code. Should I clean the MAF and then clear the code?
