1997 Pontiac Bonneville - Three blinks



Hello. I have a pontiac Bonneville 1997. Engine suddenty started to shiver on acceleration. Check engine light blinks for 3 times then gone.


That means you have a severe misfire

Could be due to overdue plugs and wires, could be ignition coil(s), injector(s), could me many things

Do you plan on fixing it yourself or bringing it to a shop?

If you don’t know when the plugs and wires were done last, replace them now. Buy only the plugs listed in the owner’s manual.

When you remove the wires, pay particular attention to the coils. If any of the coil towers seem corroded, replace them. If any coils are visibly cracked, replace them.

What engine?

How many miles?
