imran and faisal do u both own spectra? if ys than make sure it's air intake in completely open means it should not be blocked coz many mechanics half covered the air intake to get pick on cng(********).once it is completely open than tune the gas towards lower side from that nut of cng kit which has got a spring underneath it. m not sure about its name but i think it is called T nut.gas ko ziada band karna hai us nut say means tight karna hai and idle rpm should be less than 1000 after adjustment.one more than its very sensitive on gas and little bit up down of pressure of cng pump will effect its tuning
