    yes the filter WAS pretty dirty even down into it a bit. I pulled it. as far as pressure maintaining 40 I will check that again tomorrow. I left the gauge on for a couple of hours today while I was running errands and it dropped to about 31 from 38. that didn't seem terrible for 2...

    Yes I need to have it scanned for sure. I replaced the iac module and it iis better. it still stalls out and needed to be re started and revved a little, then it tryyys to idle. I got my hand near the open intake and cut a little air entering the TB, it stalled immediately. it did idle...

    Thank you for the link. I'm tryyyying to make it to Boston for "sail 250" this weekend so I'm trying the Ford part today. from all I've read its identical. ? much like the fuel volume control valve the NR-1 is used in many applications and not 200$ thru auto parts dealers.

    I just removed the IAC module, its pretty spotless inside. when I turn the key on while its plugged in holding the valve, it does NOT move at all. there iS power getting to it. this motor has about 100 hrs at most

    yes it is mechanical although the parts look up pages I use(merc) shows a second fuel pump near the filter, for serial # over 330000 this does not have one. just the cool fuel pump.

    OW359972 as I said it ran great all last season. it did start hard the last couple times I had it out but that's it. this is why I went and did the fuel pump and regulator. this is a cool fuel system also.

    I can ,, somewhat. if I pump it some it will rev up, then it wants to quit again if I let off the throttle. or it will poof pop and want to quit..

    I just replaced the fuel pump and regulator and still the same. 43 lbs while it primes 39ish sitting. could this be from a bad IAC valve valve??
