944 starts and stalls

Im driving my newly fixed 1986 944 n/a for about 1.5 hours, and my car starts to jerk, as if the engine isnt getting enough air. I stop, and then go again, and it makes a popping noise and stalls. When i try to start it, it starts and immediately dies. When i give it gas, it doesnt die, but makes a popping/clicking noise. I know the engine itself is sound, and the plugs are brand new (engine used to start immediately and smoothly). It must be a problem with the fuel or air intake. Can anyone help me?

On the next dark and rainy night, open up your hood, and start the car. If you see a nice blue light show across the top of the engine, you need new spark plug wires. They will make a nice pop and crack sound as they arc.

As for the car starting, and immediately dying, try replacing the Fuel pump / DME relay. This item will also kill the car when they get hot sometimes... $25 part, you should keep one in the glove compartment anyway.

Good Luck

When was the last time you changed your timing and balance belts and/or cam chain and tensioner?

Intake leak.... check the boot for cracks or loose. Also check the hose under the intake for cracks coming out of the idlestabilizer that connects to the intake.

wild goose chase! I've got a feeling it's the throttle position sensor because when he first started it and took off, the cold temp was fine for the enriched mixture, during the drive the car warmed up and when he was slowing down and back to a an idle situation, all hell broke loose.

usually a failed rotor will show problems and progressively get worse.

Is it possible that the engine coil is bad?

Not likely. Few ever are. I have one from my 55 chevy that still works.

Popping inside the intake is from the spark plugs firing prematurely. The only thing that can cause that is the rotor has turned on the cam shaft.

Then this could also be a timing belt problem -- stripped teeth.

A friend of mine had the same problem on a 88' 944 it was the fuel regulator.

ok, thanks guys, problem solved.

the bolt that holds the rotor to the camshaft magically disappeared... maybe it wasnt tightened well during the head gasket change.

Good feeling when the '44 runs again
