I have deleted the radiator on my mcx nytro. The radiator used to help block the snow that gets in through the open holes on the hood. Well, I was in some deep snow last weekend and noticed that I had a bunch of snow covering the throttle bodies, vacuum lines, mci box, etc. It started to run funny. I'd have to really ease into the throttle, or it would cough and sputter intil I let all the way out, then really eased into it. I'm going to pressurize everything today and check for leaks, but here's what I think could have happened. I was getting moisture throught the prefilter and into the system, with the cold snow covering all the lines that contained some moist air, condensation would occur on the inside surface of the lines, causing alot of miosure to build up in them. Just as others have stated, I think this was my problem, since the efi box checked out okay.
Edit: My problem was most likely due to a cracked exhaust manifold where the 3 into 1 factory welding is located. Hope this isn't something I'll be dealing with often.
