Hi guys, I am new at this, not sure if I'm in the right area and I did post this question already but can't seem to find it now. Has anyone seen a problem with engine running in normal idle condition at one point then increasing up to 4000rpm and "burping" at that rpm like it lost a cylinder. All cylinders are sparking so I'm guessing it's a fuel problem. Engine may be running slightly lean right now, is there a sensor maybe detecting that?
