My Toyota Carina E (petrol, 1995) failed the MOT's emission test. The results are listed below and would like your expert opinion as to what do you think is wrong. Any ballpark figure also on how much you think it would cost would be greatly appreciated.

Second Fast Idle Test - FAIL Engine Speed - 2599 RPM PASS CO - 2.58 % vol FAIL HC - 352 ppm vol FAIL "\ - 0.935 FAIL

Is my car destined to the scrapyard?
