Hey guys I have a 89 Vert with 76k miles and 25k on a stage 1 rebuild. Its been dying on me when I come to a complete stop and hard as hell to restart. I replaced the TPS and it doesnt die on me anymore just sometimes takes a few cranks to get it started. I dont remember my last FC being this hard to start. My dad bought this car in 2000 and is the second owner. He says sometimes its just hard to start. Is this a normal problem? Also an automatic. I have the papers from the rebuild.
