Re: Sputters, shudders or stalls sometimes
The inconsistent running portion of your symptom description sounds to me like a TPS (Throttle Position Sensor) that's failing.
You can think of the TPS as an old-time stereo volume control that's attached to the engine's throttle body: It basically tells the engine's computer exactly where the gas pedal is. When it gets old, it can start sending inconsistent information (kind of like a dirty volume control on an old stereo; lots of static in the sound), confusing the engine control computer.
Thankfully, the TPS is fairly cheap and easy to replace.
