Well I decided to power wash the engine compartment a couple days ago. After I let it sit for as long as I could, I started it up and it was running rough. Now before the power washing it was running smooth. So I figured water has gotten into something and is causing the hesitation.
After running it a few days it has mostly cleared up. It runs pretty good after it starts, it's just starts rough. I'm thinking it's possibly the throttle position sensor. I unplugged the MAF it dies. So I think that's ok. The IACV has been recently cleaned since the recent new injectors. I have yet to test the TPS. I'm just looking for a few ideas before I start diagnosing tomorrow. I have done some searching but was wondering if anyone else has run into this?
