I have a 1991 starmist GSI which has been family owned for 9 years now.
She has run a magnex with decat and a courtney chip for about 4 years now so i know thats unlikely to be the cause, but just latley, the engine warning light has been coming on and once on, the car just does not perform. Once the engine is turned off and restarted, the light goes out but comes on again 5 miles later.
So i did the DIY diagnostics and it came back with the code which corresponded to the Crank sensor not sending??? I think it was code 16 but cant be sure.(Knock Signal circuit )
Can anyone suggest how to solve the problem please including cost of relevent sensor and where the hell it is!!
thanks in advance
