so yea i take it to a near by auto zone to pull some codes out...
everytime they try to read it it says error check the connection......
this has never happened before and the just got done pulling codes from a different car...

 

now i cant tell whats wrong with my car


i replaced one coil 2 months ago .... could the other coil have gone bad from the stress the bad coil put on it??

 

I suggest you go to another place and see if they can read the codes.

 

ive seen this problem in the past dont recall if it was on this forum or not, but some readers have trouble with our ecu's...

 

I'm betting it's the reader itself, not the car. I would do as suggested above and go somewhere else. Mine read just fine at Advance Auto.
