I’ve been having the problem for a long time that my LT1 machine when it’s warm runs from 70 km unround, when it’s gas, it usually swallows up and only takes up the gas a short time later. If you stay constantly from 70 to the gas, this doesn’t happen, even if you start slowly like in traffic jams. I’ve also observed that when it switches into the overdrive and the speed keeps the same happens. At speeds below 70 km there’s no problem. chon several times the candles and cables exchanged, 2x Optispark, head seal renewed, but problem is not to get away. Who can give me a solution here ?
