My n55 has been long cranking out of nowhere last few days -

Then today after it did it I got check engine "operating at limited capacity "the war omg went away Nd there is nothing in my systems check at all now

Should I be worried? Maybe hpfp?

I got the half engine icon but went away -

Sounds like hpfp symptoms to me. Long crank + code + intermittent half-engine light is usually it.

Lol omg I see your point. It hasn't done it again and no more long cranks. So not sure what to do (Fix before it goes or wait )
