All these lights came on today for the first time.
The only code I have had was p0401 . It’s been on & off since I’ve had the car.
I’ve replaced the Egr valve which the code is for.
The code p0401 still would come and go. At lights it will sometimes stall. When I first start the car the Rpm’s will fluctuate.
this doesn’t happen all the time. Sometimes the car will run fine for a week or 2 sometimes a-month or 2 .
The code was off for about a month and then...
