Hey guys I'm new to this site. I have gt40 heads and intakes. Comp cam .512 lift 114 lobe sep ration. Double comp cam springs 986-16. Stock 1.6 rockers. Smog delete and egr delete. New 255 walbro fuel pump. New fuel filter. New distributer and coil. Changed injectors still stock 19#. Maf from 94 3.8l mustang and a9l ecm. Also changed fpr. But I'm having a problem when I first Drive car in first gear all the power is there all the way to 5500 rpm then when I slow down and try to drive it sputters at me. Until I drive like a grandma for 2 mins then it's got power again for a quick jump through first gear. Any suggestions
