    E30 cuts power when on full throtttle

    As when i get to 3rd gear and press down on the gas pedal the car studders, check engine light comes on and as i get off it cuts out. This continues into 4th an 5th gear. Is it a govern on speed or a bad MAF

    What fault code(s) is stored in the DME?

        search e30 "fault codes", or e30 "stomp test", either here or in google. you will find instructions on how to read your DME's codes from the check engine light. no code readers necessary.

                  shouldnt cause that problem i dont think.

                  I would have guessed a throttle switch

                      Check plug wire connections, measure plug gap, etc.

                        Once again... What fault codes are stored in the DME. They will probably provide a clue as to the cause of the loss of power.

                            jlevie the code of purge valve is no longer the culprit i drove the car just now and checked the code again i got the code 1261 which is fuel pump relay control. would that be it?

                              1261 - Fuel Pump Relay Control code indicates break or short circuit associated with fuel pump relay. Test for proper signal on number 3 pin on DME. It can also mean that output stage of DME is faulty (Motronic version 1.3 only)
