01 Jetta VR6 Misfire/CEL

Hello everyone. I hope everyone had a happy holiday. I have a 2001 Jetta GLX VR6 76000 miles. I had the check engine light come on a few times in the past 6 months. The first time it happened it was raining really really bad and my car was parked in a large puddle. After taking it to the dealer they said I needed a new coil , the tech brought me into the bay and took a hose and sprayed a jet of water under the intake area and the engine seemed like it was going to stall but the CEL did not come on. I had a bad experience before with this dealer so I did not replace it and the car ran fine for 4 months. Then the light came on again when driving down the highway the car was running fine this time my buddy from a Honda dealer scanned it (to save 80 dollars). The code was (p1152 accell pos cirt. Low input) I reset it and the light came on a couple weeks later and this time took it to a different dealer and 680.00 dollars later replaced the coil after they advised me to. When I picked the car up the car seemed like it was running funny. Around 3000 rpms in 2nd or 3rd gear the car felt like a flutter, the more I drove it got better. The service tech told me that it most likely it was the cold or the gas, it was like 10 degrees. I know that Jettas run really bad in the cold (this is my 2nd Jetta) I dropped a can of dry gas in and its been running ok since knock on wood. My question is the light was on a total of four times. Does the code(P1152 accell pos cirt. Low imput) have anything to do with a coil problem. Because the light was already on with that code stored and then when it started to flash on another rainy day I new it was missing firing but when they scanned it would they see two codes for two problems or did that first code clear when the car misfired a 2nd time.
