I have a 1990 Volvo 740 GL 230F and has the fault code: 1-2-1.Does anybody know how to fix this problem?.I bought a Haynes Manual but it doesnt tell what to do.Brought it to an RACQ accredited mechanic and he was not able to fix it either( He was looking for a computer box or something to plug his analyzer is but he did not know where it is).So I ended up browsing the internet and found this site. I hope you can help me with this problem.

Thank you,
