I have replaced the: Plugs, Wires, Cap, Rotor, Fuel Filter, Ignition Coil, Idle Control Valve, Computor. When my Porsche gets going after 20-30 minutes it starts lurching and sputtering like a fuel issue. All has been checked and still the problem persists. This happens after 20-30 minutes of driving. Thanks, for your help!

Sounds like a possible DME Relay. Get another one and verify problem.

Is that the relay under the seat? Bill Archival

What do you mean you've replaced the computer? You mean the entire DME module??

Anyone else think maybe a cylinder head temp sensor? mine was getting progressively worse driving around to the point of stalling, etc., changed the sensor & it was so much better.

Hey Gents, I changed the Head Tempature Sensor and the problem has not occurred. I am hoping this was the answer. I'll keep you posted. You guys are awesome! Cheers, Bil Archival.
