Hello everyone. I'm brand new on turbbuick. I have a turbo GMC Syclone that is 100% original. Would appreciate hearing from all Syclone owners. My question: what is wrong when motor backfires through intake occasionally, the full blast acceleration is anemic (sick) at any speed. New plugs, wires rotor and air filter are new and didn't work. Idle is rough. At 200,000 interstate miles, hot oil pressure is still 60 psi using 5w20 synthetic!
