I ran my 87 GN at the track and after going through the finish I only had engine power at idle and boost.Had a tough time getting back to the pits.I let it cool down and it ran ok for about half a mile then the power went away.Got it home checked fuel preasure 40psi changed plugs they were all suty and running real rich and blowing water out the exhaust.I dont think its anti freeze by the taste just water.I changed the MAF to a LT1 with translater it runs but runs ruff and rich.No codes on scanmaster.Pulled gas tank and cleaned it thinking I might have water in the gas but havent tried it since.Any ideas?:dunno:
