So this has happened once every several miles. I'm cruising along and all of a sudden the car jerks. When it does this the CEL flashes and more recently I noticed the Fuel Economy Gauge spikes to reading high MPGs. The tach and speedo are not affected. This all happens in less than a second, the car shudders, and it's done and the car continues on as if nothing happened.
All new ignition parts: plugs, plug wires, cap, and rotor. Low mileage, known working CPS.
Based on what I've read, I'm thinking the TPS might be bad. It's adjusted properly, but I'm thinking that the ECU is getting a faulty reading that the TPS is closed (or less than what it's actually at) and reducing the injector duty and the car is leaning out, causing the economy gauge to spike and the car to jerk.
Any other ideas or input would be appreciated.
Thanks
