I will try to get better picture of the fuel filter. The new one I bought came with 4 of those plastic clips seen in the pic you attached. Are tose what was missing so someone use a zip tie to replace one of them?
UPDATE on IMRC:
I have pics of this but need to upload them still. I got the IMRC out and replaced all of the white grommets and got the arms in there properly. When I turn the key you can hear it moving back to put the stops on the stop screws that are there, which I assume is the closed or idle position. I'm sure it moved because when I put it back on they were not in that position and after I turned the key they moved there. I am still having some idle and rough start problems. When I say rough start I mean that it shutters when I first go from a stop then once it gets more gas it will even out ans also that it revs pretty high after warm, but not as bad since I fixed the IMRC (in fact you can hear and rumbling air sound from the muffler(?) when it drops from the rev back to normal idle, which sometimes is pretty quick, like something is sticking). When it's cold it will idle high and basically drive me down the road. When it's idling high (brake keeping me stopped) it goes from a stop without the shuttering, because it's reved up I guess. The rough idling is the same when the engine is cold (going from 500 to 1000 rpms, up and down and nearly stalling. Have to put it in nuetral for it to even back out so it only happens when in drive.
You had put this on a seperate thread:
"That sounds like a vacuum leak... Check all those vacuum hoses ... There´s a vacuum reservoir - its one point to leak... there should be a little backpressure valve
in t-line connector --change it ...
Check those hoses from diagram, and then you see that those are working correctly... "
I am going to take the cowls back off and check all the hoses and the check valve. Is there a way to figure out if the check valave is clogged? I will take it out and inspect it and look for more loose hoses. Weird thing is I don't really remember it running as badly when before I fixed the vent issue and pluuged the hose back in that was causing the only in defrost thing. Maybe it did, I just hadn't driven it enough but I realy can't remember it being this bad. I am hoping it is a vacuum thing that doesn't require what someone else said which is the isolator bolts inside the manifold. It seems like taking the plastic manifold covers off is challenging but I'm willing to take a look if I can't find a vacuume leak. They also said the butterflys that are controlled by the IMRC are internal. Would that require me to get inside there to check?
