I recently had the little filters removed since I kept getting oil coming out from the oil catch can. Yes I dropped the oil level to 1/4 of a tank. I put it back in the shop and they routed the hose from the oil catch can back into the air intake and the block off plates were added. Now I get an engine miss between 2-3,000 rpm's. It feel like the engine want to cut off when it idle. So Riva or anyone please help. I am having so many problem with this Stage 1 Kit when everything should be tested before it is shipped to the consumer. The only parts worth the money is the Ride plate (known as the bat plate) for the rest I am sad to say don't waste the money. I haven't tested the intake gate not available yet.
