I have an 08 MDX with 239k on the dash. Car after getting up to 30-35mph it begins to hesitate. Codes are p300-306 I changed plugs and coils. Transmission specialist diagnostic test shows trans is good. Codes have gone away. It when I try to push it the sh-awd lights starts to blink. Any ideas...

I RECENTLY GOT MY MDX.. BUT I GOT DESPRATE AND ENDED UP WITHT THE BASIC. NOW THAT I SEEN HOW THE ASPEC LOOK TOTALLY REGRET IT. I WANNA PUT THE Aspec REAR BUMPER CAN SOMEONE GIVE ME AN ADVICE? IF IS POSSIBLE OR NOT.. THANKS
