Default High Hydrocarbons

Hi All,

Wouold appreciate any thoughts/advise on what I quess could be a problem.

Took my 86 for emmissions inspection and it passed, but barely.

Results were:
HCppm: @15rpm 129 (limit 135) @25rpm 130 (limit 130)
Co @15rpm 0.31 (limit0.76) @25 rpm 0.45 (limit 0.80)
NOppm @15rpm533 (limit 1052) @25rpm 477 (limit 957)

Do I need to start freaking about my mixture being too high with chance of ruining my engine !?

Different posts suggest the Oxygen sensor but that it could be anything to do with the Motronic system.

I have had the car 2 months (how time flies), bought in TX and maintenance records show TX inspection about 1 yr ago with very low hydrocarbons. Wonder what happened. The car has a Autothority chip.

Do you tink I need to take it to a shop to have them check the settings ?
Any recommendations ?

Thanks

George
