Hi all, I've got a rolla gti thats been in my garage for 6 years, owned for15, after timing belt snapped(1991 late version import). Spent the last few months (and too much money) restoring. Got it running but only problem now appears to be the knock sensor, matched code and removed the sensor and it is damaged. Went to toyota and checked online these are over£100 new! Was wondering if anyone has or knows where i could get one, or if they are the same part in all gti's or even mr2's etc? then i could try and get one from a breakers? My sensor that i removed has a few markings on it. Large letter: M , no: 71 with no:145 underneath and no:00412. Any help much appreciated. Andrew
