Re: F4i help

try switching up the packs to see if it will change cylenders. the spark may not be strong egnough, pull the plug and get a flash light look down into the cyl also check all your connections.

Re: F4i help

Once again.....Fuel Pressure Regulator.....When it starts going out, it will dump fuel into the #2 and #3 cylinders. Sometimes it'll dump more into one or the other. Check the line that runs from your FPR to ur throttle bodes at #2 and #3....If that line is getting fuel into it, then the FPR is most likely going out. Simple fix.....=-)

PS: Even if u put new plugs in it and dont realise the FPR is going out. When u try to make it run, it'll foul the plugs pretty damn quick
