okay next question for the person who is new to monteros.

I was going down the highway and it started to stutter then it died.
I rolled off the ramp and then it would start idle really low like 250-350rpm and if i gave it throtlle it would very hesitantly rev to maybe 1200 rpm max.
and then die.

I turn the key to accessory and couldn't hear the fuel pump and it kinda felt like a fuel pump so i changed the fuel pump but that wasn't it.

before this sometimes when it was cold out it would idle ruff but it would smooth out after a few seconds. so now I'm beginning to think it must be some kind of sensor.

I grounded the number 1 terminal on the edu connector and turned the key on and counted the check engine light blinks but it just never stopped blinking.

there isn't a fuel pressure port so I can't check if its fuel and its a lot of work to pull the intake and check all the plugs for spark

but the engine sounds really smooth for the most part just idles really low then if i rev it up a little it sputters and dies.

whats the next step for trouble shooting these engines?
