Seriously, this has already been asked, and I will reiterate. You need to have the car scanned for codes.

Excellent. I think high liklihood this will resolve your issue, or at least complete a necessary step.

Yep, that'* tens of thousands of volts of electricity crossing to ground since it has nowhere else to go. At least you're alive to tell us about it.

This is when it is most likely, under high load at high RPMs.

I agree. Also we'd love to know how many miles are on these plugs and wires.

Sorry , I don't know . Like I mentioned before , I bought the car only 6 month ago, and I don't have the history .

If the car is still actively throwing a P0332 as mentioned earlier in the thread, it would be good not to push it until this is resolved, as this is for a knock sensor.

As many have said, if the service history is unknown, the basics like spark plugs and wires are good. Next question would be to check to make sure it'* not losing any coolant. That is one way that a failing UIM can show up is by driving misfires.

Hi guys
I return with update ...
I replaced the old spark plugs and the wires with new original ACDELCO plugs and wires .
the "service engine soon" light still blinking when I get high RPM .
the problem don't solved :(

Have you done anything about the P0332 Knock sensor code?

I already replaced the knock sensor . It'* new.

Information like that we need to have at the beginning of your post.

So, you have replaced all spark plugs, wires and your knock sensor. Have you cleared the codes and driven it to see if new ones pop up?

Sorry.
Yes , I replaced the plugs , wires and the knock sensor .
I need to reset the system ? The light only blinking and turn OFF .
