Heya,
Lately my engine has been cutting out for maybe half a second before it gets warmed up. Usually I'm cruising along at a steady speed and the engine stops powering the car for a moment, or like someone described, it "skips a beat". Sometimes it's pretty bad, sometimes it doesn't happen at all. But it never happens once the engine is actually warm. What could it be? It seemed to start a week or two after I installed my FPR, I have it set at 46psi now. More fuel kinda makes it seem worse, but I'm not really sure. Bad spark plugs or wires maybe? But then why is it perfect once it's warm? Thanks.
