Question for you, have you recently dis-connected the battery for any reason?

I am having the same problem and yes we have unhooked the battery


Let me guess, this problem started after you unhooked and re-connected the battery? To fix, disconnect fuses #10 and #28 under the hood. Completely remove your throttle body, very easy and yes you can re-use the hard plastic O-ring many times over. Use a sensor safe spray cleaner like Seafoam on both side with a tooth brush or rag only. When done and put back together, hook the fuses back up and done. Very common problem, due to a dirty throttle body. Computer thought it was clean when you hooked the battery back up.
