Fuel Pressure Problem With Video
Ok, so after running for about an hour, my car does this. stutters, and will slowly stall out at idle. can someone confirm if this is my fuel pump.
sorry about the camera moving, i was trying to get a decent shot of the guage. and when i pull away the stuttering is not me, its just doing that under about 1/4 throttle.

a couple of things to remember...when car is parked,and putting load on it you are creating different vac load..
take it out on the road and drive it,and see what it does....
my 190plh did what yours is doing(ran my tank low,and burnt it up?)...so i say it's a good possibility.

gauge is under hood[:@]. when im driving it gets a little better but still feels super lean. would a vac leak be causing my f/p to drop and why would it be temp. related?

underdrives. around 800 rpm its fine. i thought that was my problem (pump not getting enough voltage) but even at 800 idle it still does it.

Can you hear the pump prime?
After it cools off, will it restart and then go through the same chain of events?

it will restart, but with a bit of hesitation. it will prime, the way it primes sounds kinda like, wuAH... hard to desribe. it sounds unhealthy. after it cools, it will be ok for about, 5 minutes, then it repeats. when it is cooler outside it doesnt happen as often.

Now after it dies out does it restart or no?

What's the f/p reading when cold and then when hot after it dies and you restart it.
