Whats wrong with this car I give up!!!!thinking about scrapping it just because I'm so mad at it! Spits and sputters after starting and backfires if you give it gas. Now a little background car had overheated due to intake maniflold gasket leaking, meticuous changed it but never could get timing right i guess. I set to 6 degrees and appears to be pointing at #1 start and runs fairly smooth with tan wire by Ac unplugged but has some missfirin or hesitation through rpm ranch. but if you shut off and replug the tan wire it spits,sputters tries to catch itself and dies as soon as you start it. I fixed all the sensors and it currently displays no codes. had about 40lbs fuel presure and new computer any thoughts?

 

yea set the timing correctly if that fails scrap it. :/
