i jus bought a 1986 svo and i believe im having pinging problems.... under full throttle and top boost it begins to chatter then bogg down ... i believe the knock sensor is doing that but with timing at 10,new plugs, wires and premium gas with the priemium swicth on; yet it doesnt do it when its switched to normal!!!!.. do i need a 255 fuel pump? it also has problems idling on startups and once warm it sometimes idles at 3000 until i rev the motor then it returns to normal....what can it be, where can i start? someone help me please

Start with a code scan and a tuneup. Also how much boost, what is the timing set at, and what octane of fuel?

My tc was pinging badly,i dropped timing to 12 degree timing and unpluged the ks. Now it running perfect and as more power. One thing i noticed was the factory intercooler bracket mounted on the exhaust manifold, that bracket wasen't tight so it was brobably knocking enought to make the ks going crazy so it took it off.
