so i went from a ls1 to a lq4. kept the ls1 cam. got to driving it and the ses light starts flashing at highway speeds only. when i give it some more throttle it stops, at city speeds it doesent come on. its not misfiring at all so whats going on? the scan shows multiple random misfire. i havent had it tuned yet. im gonna get it tuned but i dont want to overlook something that might be costly. any insight would be appriciated
