4.6HighPerformance

hey guys, im running a 100 shot on my gt and i keep burning the plugs... they are the autolite ht0 plugs which are one heat range colder... my air/fuel ratios are on the rich side, is that why i keep burning them?? all motor the ratio is about 13.2, on the spray 12.4, and 11's in 5th gear... is it too rich, is that why im burning my plugs??

thanks, tony

not too sure about nitrous but i dothink your supposed to be running lean

but the plugs usually burn when there is too much fuel, right?

do you have any pics of the burned plugs

try race gas w/ the nitrous seemed to work on all my other cars

no i dont have pics,, but the are pretty dark, and missing the closed tip completely... and the spark tip looks like it was grinded down...

Is your timing right?

rich is not going to dissentigrate the end of the plugs.

there is lots of info out there that can help you read your spark plugs. If anything it's too lean.

my air fuel ratio is good, might be my timing...im gonna retard the timing a little bit... im running the jlt 91 oct tune with the 100shot, but i know my a/f because of the wideband i have on the car...

Two pieces of advise...


1. Check the timing.

2. USUALLY when plugs are black, the engine is actually running too lean... NOT rich... Your motor is running rich if there are excessive carbon deposits... In this case, just get a can or two of brake cleaner and a brillo pad...
