i traded my car for a del sol with high c:r sohc. When i first traded it ran fine. Now im back in my state which is 2000 feet higher above sea level than where there this car was tuned. Now it runs funny, light throttle cuts and is choppy like the timing is off or its missing. So i went to check my spark plugs and there is like red dust type stuff on the ends of all the plugs. kind of like rust color. i sprayed with starting fluid and it ran off. I havnt driven my car yet to see if it changed but where would this red ---- come from?

SpankedYA!

Its the additives in the gas.

would it have anything to do with the stutuering of my car under light throttle but any throttle over id say 30% and its fine....
