I have a 2004 Spider Lusso which has a couple of problems that aren't able to be fixed at a local level here in Australia.
When slowing to a traffic light the car develops a harsh kangaroo hop under 40 KMH or so in low gear and whilst idling at the lights I'm getting an infrequent missing.
The service team have installed new air flow, plugs and coils, fuel pressure regulator, throttle body and injectors have been flushed. These have failed to fix the problem.
There are no fault codes on the computer.
It has been suggested that injectors be replaced, the labour would be high to pull engine out for this, a new accelerator potentiometer and check and clean all engine sensors and earthing on account of bad connections might drop the voltage to 6 volts or so that could cause the problems but not register a fault code? It's a 2 litre JTS engine.
Please help as we are clueless on our next move. These problems ruin the driving of an otherwise beautiful car !
