lat night my car started stumbleing at pretty much all rpm ranges and I think it' could be wire but havent had time to check yet.

would this give me a check engine light or not?

thanks.

 

Mine sure did. A flashing one!

 

I didnt get one till i had about 2 or 3 burnt wires..but all 3 where going out around the same time i think (with in 1 week)

 

Yea it can set off a high voltage warning in your opti. By the time you see that code though you may have just started to burn out your opti. You see with a burnt plug wire, if the power does not jump somewhere it may jump inside your opti thus burning it out.

 

well i don't yet have a light and I just drove thecar home from the track(15 miles) and parked it ,I am gonna check the wires quickly at lunch time and then I will know alittle more about what going on and if it's awire or opti or even an MSD box or coil problem, thanks alot guy's!

if any one else has any Ideas please keep em comming!

Thanks

 

Well it is confirmed! it is a burn't wire! thanks for the help guy's!

 

Doesn't necessarily set a light or store a code...my #6 wire was bad, no light/no code. In the dark it was arcing all over the place and causing the coil to arc as well. Changed the wires, and the coil for good measure...

 

OBD1 will not set a ses light for a misfire...i had two burnt wires and no light came on, however, OBD2 will not only tell u a misfire is happening...it will tell you which cylinder is misfiring...nice
