My Volvo 440 1.7si auto 1993 failed on emissions. The mechanic said this can be adjusted using the c.o. potentiometer. But he couldnt find it. He looked through the Haynes manual and it's not where it says it should be. He then said he thinks my engine has been replaced with a 2lt version. I looked for the engine number; when I got home; where it says to look in my owners manual. On my ownership papers my engine number has 1 letter then 12 numbers. Where I looked it had 1 letter and 6 numbers. Is this right? Is the Mechanic right?
