Nissan Repair Questions? Ask a Mechanic for Answers ASAP
I am sorry for the long wait
off idle and driving will it drive fine at speed ?
will the light only come on or blink at idle ? or when driving it the light will blink ?
usually when the check engine lights are blinking it means the engine has a misfire in it which can be anything from a vacuum leak to valve timing being off to a spark plug or injector issue causing a misfire
are you planing on fixing this yourself ? or looking for a good idea before it goes into the shop ?
it could be but usually would set a code
i would fist make sure there are NO vacuum leaks at all at idle spraying around the top of the engine with some carb cleaner with the little hose on it and see if any area you hit the idle changes or the engine revs up or stalls
if there are NO vacuum leaks at all check the spark plugs and also be sure none of the wires are cut or split or damaged to the spark plugs
