Hello, my name is ***** ***** I'm here to help get your problem solved. This usually means you have a dirty throttle body which will cause airflow restrictions during closed throttle such as idle, slowing down, ect. This can cause hard starting, low idle, and stalling. The fix is to get some throttle body cleaner from parts store, spray onto rag, then use rag to wipe out throttle body good. As far as the misfire up a hill that usually means ignition problem but since you already replaced the whole ignition system I'd start by monitoring fuel pressure as it sounds like a fuel issue. Let me know how it goes or if you have more questions, thanks.

Due to age of vehicle I'd like to ask a few more questions. Does it always restart right away?

Customer: replied 2 years ago.

yes, sometimes it takes a try or two.....

Expert:  Dan replied 2 years ago.

This vehicle shouldn't need the throttle body cleaned, I assumed you had a newer vehicle before asking. Next step is monitor fuel pressure during problem. If fuel pressure is steady I'd replace the complete distributor. If fuel pressure drops during problem then replace the fuel pump. Let me know how it turns out or if you have more questions, thanks.

If your check engine light is on I'd start by checking codes.

sorry for taking so long to get back to you. How can we check/test the fuel pressure?

Expert:  Dan replied 2 years ago.
You will need to get a fuel line adapter and t into fuel line where it connects to fuel rail under the hood. Let me know how it goes or if you run into more questions, thanks.
