1995 Oldsmobile Aurora spark

Hello -

To better assist you please tell me your engine size in liter and the miles you have on the car.

If it were me based off of what you said, I would swap the coils and see if the problem moves. If so then it is the coils.

But again. Please let me know the above.

Hello -

Do you know how to check the codes on your car? If not I have attached how.

Without these special tools, installing a jumper wire between terminals "Pin A" and "Pin B" causes the malfunction indicator light (MIL) on the dash to flash any trouble codes.

I am going to explain it here also.

I have attached how you check for codes. See if it makes sense to you. The big thing. . ...DO NOT START THE CAR!

You basically put as a jumper wire or paper clip and jump from the A pin to the B pin. Jump them together.

You then turn the car on to where JUST the lights on the dash come on ONLY. . ...DO NOT START THE CAR!

Watch your check engine light.

The first flash is the first number and the second flash it the second number. So you sit with paper and pencil and count the flashes. It will flash the same number 3 times and then go to the next if there is one. It should always start with 12. So for 12 it will be:

Flash (1) pause flash, flash (2), longer pause. . .. Flash (1) pause flash, flash (2), longer pause. . .. Flash (1) pause flash, flash (2), longer pause. . ..

Now from this point on watch and count the other numbers. Say it is 31. It would be:

Flash, Flash, Flash (3) pause flash (1) longer pause. . .. Flash, Flash, Flash (3) pause flash (1) longer pause. . .. Flash, Flash, Flash (3) pause flash (1) longer pause. . ..that would be code 31.

The second you see it repeating itself, then turn the car off and immediately remove the paper clip or jumper wire so you don't forget.

Again - I cannot stress enough. . .. . .DO NOT START THE CAR.
