Hello, I have a problem on my 240 turbo 83 and I hope to be able to explain it:
Some times (when motor warm) On idle, I accelerate and begins to vibrate the motor I have no power, and I press the pedal a little more the motor runs well. WHere to start to check (is fuel injection, or ignition, voltage, grounds, etc) Thanks for any advice.

Edwin

Possibly the sensor plate in the fuel distributor is occasionally binding when it's in the idle (or low-flow) position, causing the engine to momentarily run lean. Added throttle dislodges it (unsticks it), the mixture returns to normal, and the engine evens out.

Of course, when chasing a problem like this you must first confirm that the plugs, wires, cap, and rotor are all in perfect shape.

Also run some injector cleaner through it.
