My car has been acting rather strange lately, I found that if I cruise at about 3200 rpms for about 5 seconds then the check engine light will start to flash and the car will start to sound like it is running on very little power.
I had this happen on the freeway, the light flashed for about 20 seconds and then went away and the car drove fine again. I then put the car in 5th again and hovered at 3200 and it did the exact same thing. This time it left the check engine light on and the codes were for random misfire and misfire on cyl#4.
Don't have much to go on as to why this is happening. The only thing that happened specifically to that cylinder is that an extension arced from the battery to the #4 spark plug coil hole in the head. But i didn't think that would cause this. Unless the arc could have affected the spark plug.
It's really weird that it only happens at about 3200 rpm. If I run it at 2800 or 4000 it doesn't ever throw a code.
Hopefully you guys can help figure this out.
Thanks
