I have my 90 gt an I just put gt40 heads with trick flow valve springs an 1.6 roller rockers on it with 42 pound injectors I have a sct 3000 mass air meter tuned for my old 30 pound injectors so its not tuned for new injectors but I needed to start it to get it warmed up so I can retorque head bolts an adjust rockers but when I went to start it it wouldnt start unless I held throttle to the floor when I got it started I timed it turned it off an the same thing when I went to restart had to hold it to the floor do you all think it would be because the mass air meter isn't tuned for them injectors yet everything seemed OK once started just idled a little rough any input would be appreciated thanks
