I actually haven't fixed my hesitation yet. I reset my ECU a couple times and the car ran fine for a few days, but then it came back on. I have a constant CEL now due to a "Misfire in Cylinder #3". As far as the hesitation goes, I might have a small leak around one of the seals or around my MAF. So Im going to do the soapy water thing and see if I see any bubbles. If so, then I know what the problem is and will try to make the seal for the MAF sensor. While Im doing that, I might also try to adjust my stock fuel pressure and see if that will help keep away the "running too lean" issues" the CAI is known to create.
