just bought a 95 Sho 3.o mtx, needed work, cats clogged,replaced buck and surge on accel, new plugs,wires,coil pack, still flat on WOT and anything more than half throttle. scanned cleared old codes, spark and cat stuff.new TPS better but still flat over 4000, on more than half peddle!!!!!
So my thought is knock sensor, sure could use input, been a long time since i have tooled on one of these.now i feel like a tool. still get 24.7 to 26.9 mpg should get better, the new wires are 7mm there was taylor 8mm wires on it.
Changed to Synthetic 10/30 still have stock air cleaner set up and stock mufflers other than free flow cats. HELP!!!!!!
Thank you in advance.!!!
