You need a HPFP. It's leaking. Is the tick still regular or is it random? These are all the same issues I had. Our cars "pend" codes (CEL). In other words, it hasn't quite set the CEL yet because it has to see the same issue again before it will set the CEL. Almost all here don't know that!! When they pend, they only cut a portion of the power until you have 5? key cycles (or 30 minutes of driving without another issue, I can't remember the exact time) or the you actually set the CEL. Gaurantee if you hooked up a code reader, you would have a pending code of p2178 (or 2188, can't remember). I've been there, done that.....
