i had this happen to me also. Did your car throw a cel? mine did, so i took it to mazda and they said it was a bad ecu. So they replaced it under warranty and ive been driving really smooth ever since.
ok well first off this might be in the wrong section, so let me apologize. ok next does any one recommend a method of removing black paint from an intercooler core.i bought a kit from a forum member and the core was painted black, i was wanting to know if and how i could remove the paint...thanks
