I recently posted about an issue with a rough start in the morning in my 1984 celica supra. My fuel pump was bad and I have been told it could effect cold start so I had the fuel pump replaced also there was a ripped vaccum hose on the intake manifold i was able to fix, not sure what exactly made it start better. It was perfect for DAYS then sure enough... Ive taken it to two mechanics and neither could find the problem. Could someone please send me a pic pointing out everything i would need to check that could be the possible culprit and the steps on how to if possible. I am a female with very little experience with working on cars and i just want to solve this issue once and for all and mechanics havent been much help so far so I'd really like to take it into my own hands if possible.
