ok i went and searched posts to see what was similar to my noise that is occuring sometimes. MY car seems to make a pop pop noise when it is cold only and under load. i can accelerate steadily slowly and be ok with it not popping. it doesnt pop at all when it is warmed up and running for a while. my timing is set about 15. this has nothing to do with the nitrous that is installed. this was happening without it installed and the nitrous works great. any thought? should i retard the timing to 10 or 12? this may or may not be associated with this problem, BUT it seems to have tons of juice from 3000 and above. getting up there isnt slow, but not as powerful from 3 grand and beyond. maybe it is the set up of the motor. thanks,

jim

if it is running rich or lean, what can i do to help? thanks
