i have a 1982 mercedes benz 380sec 2 dr coupe v8,,
and i was about a week ago and did the smog,,and it failed!,,

this car it was on non operation for all most 2 years,,due to some engine problem, now i fixed and i run it for 50-60 miles and went to smog,,and failed,,

it was timing problem,,and i fixed that,,i did change o2 sensor and catalik convertor,,sparg plugs,fuel gas filter,, and i dont know if this will do the trick with the smog?,, i know the emisions on those papers was very high,,

so now i cant find if it has a EGR valve to see if it opens or closes,,,

any help,,will apreciate
