  • HELP! biza gti engine trouble

    my 95 ibiza gti is running really rough, it starts and then its making a kind of popping noise out the exhaust and when i rev it it will drop by itself, it seems to improve once its warmed up but still not right.

      Or vacuum leak. Check the intake boot and hose from the back of the throttle body.

          If you've no joy with the coolant sensor, change the Digifant ECU Voltage Control Relay - #30 on the fuse box p/n 165 906 381. All dealers will have in stock at about $35 RRP. It's the central relay to the entire engine management system and a very common failure. Most common symptom is significant misfiring at around 3k RPM, but it will also cause a heap of other faults due to affecting the throttle position signal etc.
