I will do that I also unplugged tps sensor and I wouldn’t even run so I plugged it back in then unplugged the CTs sensor and it ran but with high idle then after that the computer threw a code for both of them. I’m thinking it’s either the coil or the cap or wires. The wires and cap and rotor are duralast gold (autozone) plugs are oe ac Delco
