Hello, I'm hoping to get some ideas on how to fix this issue on my car. It has 2.5 engine and 135,000 miles. When the car is cold it will start then die, I repeat this 2-3 times, then the car will start and continue to run. A few times recently the car has started then somewhat violently chugged and bucked for a bit then died. After chugging and dyeing 3-5 times it will start, chug, and then pop up the RPMS and run fine. There are no engine codes. I can hardly believe no engine codes occur because this is quite dramatic chugging shaking the entire car. I have pulled the MAF sensor and cleaned, nothing different. This does not happen when the car is warm, and I never experience any drivability issues once running. Any ides for me on where to start with this?
