When does it misfire? Is the engine light on now? Were you able to read any stored fault codes? When it stalls does it start right back up?

It misfired while am driving. The engine light is on. Yes I read the codes. It starts right back up when it stalls.
Do you have the code number? Do you feel the miss just before it stalls?Unfortunately I am unavailable for a call at the moment but we can continue here til then.Let me know.

I don't have the code number. Yes I feel it when it stalls.
Ok I have run into this a few times and it was a bad fuel pump. What happens is once the pump gets hot it cuts out and causes the miss then stall. This usually happens while driving under load.We wouild need to confirm fuel pressure at the rail to be sure.Please also post all code numbers.
