Hello,
I changed my leads and spark plugs today (one by one) on the 5.0l
When i put it in N or P it fluctuates the idle by 250rpm or so
It used to do it before but only say 50-100rpm
No idea whats up with it, The plugs were mostly black and the leads looked in poor shape so the replacements i got champion leads and NGK plugs..
Any ideas?
Thanks
check your leads are in the right positions and that all your spark plugs are fine you may have accidentely cracked one putting them in if thats all good i would suggest cleaning you throttle body you would be suprised how much of a diffrence it makeslet me know how you go
