  • Issue with WOT URS4

    As the title says, I am having issues with my car making any power WO. In any gear (2,3,4 tested), when I floor it I get some heinous backfires and the car lurches badly. Just changed plugs out as well. This didn't happen at all around 6 months ago. I checked intercooler piping assuming the issue is somewhere between the compressor and the intercooler. Can't see any cracks as of now. I assume it would be due to a lack of air getting into the engine to compensate for more gas. Anyone have some suggestions?

    Otherwise, the car runs well.

    You need to do a proper pressure test if you suspect leaks.

    Pressurize the inlet tract with the help of a air compressor from MAF hose and block off the PCV system.
    1 bar or so should do it and you'll be able to find your leaking joints/hoses.
