[89PS911]

Hi All,

Diagnostic:

1989 911 3.2 with 77,500 miles. Has always run perfectly. Motor burns a quart of oil about every 1,200 miles. Does not smoke on start-up or at other times.

Engine was out for a new clutch in March (75,000 miles). Also, all fuel lines in engine compartment replaced at that time. Ran well as always until this start-up problem developed (see below).

No smell of gas in the engine compartment or the front trunk with engine off or running.

New Bosch plugs, ignition wires (Magnecor black), Bosch distributor cap at 72,000 miles.

Have checked that all plugs and wires are seated properly.

Car starts right up in the morning with one push on the gas pedal, releasing gas pedal, and turning key. Idles at a steady 900 or so RPM.

For the first time last Saturday, after I had been driving the car during most of the day, I went to start it and it would not start up. Cranked with full power; but did not start up. I checked all plug wires. After a couple of minutes, started up again with no problem.

Situation now: Starts right up on first try; on second try, starts but seems starved of fuel, stumbles, and if I don't push the gas pedal it dies after 15 seconds. If I do push the pedal, it goes up to its usual steady idle. Occasionally does not start just after I turn motor off, but will do so after one or two more tries.

Any thoughts?

Thank you,
Jonathan
