306 accelerator problems

Hello everyone, I have the problem that the 306 hdi diesel is accelerated only to 1250 rpm and sometimes slow down, on occasion I have to stop and start again so that the acceleration disappears. They changed my accelerator but continues to fail, in the Peugeot they tell me that I have to change the computer (I do not trust me, it gives me a guideline that they know little) He did is the change of cables between the accelerator and the computer.
greetings.

The injection light is turned on when the fault? If it is so fixed in the cable maso that goes to the temperature bulb of the injector ramp you can be touching in the block and make short.

No, the injection failure light does not turn on

Czech the state of the connector from the pedal to the computer sulfate and give a can Hojo the moisture on occasion one climbs the wet shoes and accumulates.

From the pedal to the resistive accelerator it is from steel cable like the others, I check the connectors from the resistive accelerator to the computer and I see, before yesterday I was touched them and did not accelerate again.
Greetings and thanks.
