ok so I have my lq4 put in my buggy and it runs fine when cold and idles great. then all of a sudden it drops off and idles low then dies. especially after you give it some gas. I have brand new 02 sensors in it also. here is a vid of what it is doing. has not thrown any codes. any help would be awesome :) (

anyone, anyone ;) the guy who did the tune on my comp said he adds more timing into the peak curve sooner. would that be so much to make it idle the way it is and die at temp?
