I recently rebuild my 96 gst after it spun a rod bearing. I forged the bottom end and added some comp cams to the head. Since the first start up I cannot get the car to idle. It will run if I give it throttle and hold it at 1200 plus rpm's but it misfires like crazy. I thought it might have been a timing issue but I ran a compression test today and it was 150 psi even across the cylinders. I have dsmlink and thought maybe it was in the tune but I have tried to adjust values and it doesn't change anything. I don't know if I should tear down the side of the engine and check the timing specifically or not. All the values seem like the sensors are working correctly. Any suggestions will be greatly appreciated. I'm on a short deadline to get this thing going. I need to send it back to my parents house because I am leaving for the military here soon. I included a log to show what is going on.
