What is your question?
After making multiple stops turning car on and off the car will idle super low and then bounce back up and down and then just die. Then it starts hard. I'll try to drive and it won't accelerate and just repeats the cycle for multiple times before I can drive again. No codes are on. I have tested the fuel pumps,put gas treatment in it. Still has the issues.
What makes this problem better or worse?
Nothing

Hello, it sounds to me like a "hot soak" fuel condition, meaning that the fuel is vaporizing in the presence of a hot engine before it can be consumed by the engine. This can be due to fuel quality, but it can also be related to fuel tank and line pressure creating like a vacuum and preventing necessary fuel delivery. You'll definitely want to make sure everything is reading properly - from mass air flow sensor, barometric pressure readings, fuel trims -- these are things that the engine's processor utilizes to create the proper air and fuel mixture depending on altitude, temperature and environment. Hands on testing is needed to find out what is happening at the time the problem is occurring. That will be important. And diagnostic trouble codes that may be set can be reviewed and have troubleshooting performed on. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
