how do i check the cel light and how can i clear it manually without the scan tool.

also the light came on after i did the clutch. i plug ever wire and plug back in nothing pinch or cut.

i also have a clunking when i shift. it's in the rear i think my differrential mounts are shot. where can i find aftremarket bushings and **** for the diff. does energy suspension make them?
LET ME KNOW THANKS

 

don;t tell me know one knows about any of this

 

my goes on when i get gas sometimes, then jus turns off after awhile, i tend to ignore it

 

anyone else.

also i hhave a stock 240 is 87 octane sufficient will it throw a light

 

I don't know...last time I had that check light on, I've replaced the oil filter (with a 300zx na one) and it works.

And yes, my old oil filter was not even in good condition. too...old
