Dear Ray,
The 'service engine soon' warning appeared on my 2002 Nissan Maxima after servicing the car.
Worst still, the 'service engine soon' blinks when I accelerate and the car vibrates when idling or in traffic.
Please how do I solve this problem?.
I am not a mechanic, if you don't want to take the car to a service centre here is a link automotiveforums.com and link to Nissan, you will be in touch with mechanics and Nissan owners
