Stalling Issue - Help!!!...

Hey Guys...

So Like a month ago, i swapped out my 2.2L for another 2.2L while Im waiting to finish my new motor. Anyways, The 2.2L i swapped into my truck, Worked great before it went in, Put it in, got everything connected, it was Running a little rough, so i re-did the Timing, Adjusted the Idle, Everything was pretty good for about 2 to 2 1/2 weeks or so... And then i was downtown Saturday night (last week) it started to Act up when i was leaving, Almost like it wasn't getting gas, So i thought i Ran outta gas, so for the hell of it, I tried to crank it like 5 more times to start it, and it actually started, Drove 3/4 of the way home, stopped and got gas, just incase i really was running outta gas, (which i don't think i was)... Now, Since then I can drive down the road fine, but if i let off the gas in gear its almost like it wants to stall out, and if i go into Netural while rolling down the road, it stalls out complete, now sometimes if it doesn't stall out completely it dives to like 250-500rpm's and toggles between the 2, I've attempted to adjust the Idle, and adjust the Distributor every so slightly to compensate for the lack of idle or viceversa, keep in mind the the distributor is as close to center as can be, its not retarded or advanced to much, either way, i dont find it helps me with my issue.

I find i can make it Idle pretty good at approx 800-900rpm's... and even 1000rpms, to compensate for my compressor when it drops my idle. and just when i think everythings good and it sounds good, I drive away, and i don't even have to be going fast at all, and the Idle will drop really low and sometimes even stall, if i let off the gas with the clutch in, happens really at any speed.

No Problems with accelleration really that i've noticed.

All vacumm lines are connected

Things i've changed:

Fuel Pump (Mechanical) Fuel Filter Pulled the top of the Carb off, and cleaned everything Cleaned Gas Lines Pulled Fuel sending unit, Noticed the Mesh filter wasn't on it, put it back on PROPERLY... Spark Plugs

might sound stupid, But the best way to check your advance is to disconnect the vac line that goes to it, If the idle changes then its working, also you can put a timing light on it, get the rpms up a little and unplug it and see if the timing changes......thats the only two ways i know to check it

The vacumm line going to it has Suction when i put my finger over the line when its running... makes it seem abit better i think?

Would a possible crossed line in the fuel system cause this??

sounds like a possible vaccum leak or possibly the wrong hose going to the wrong thingymajigger

I would also like to know. Mine idles real low after it warms up too and it used to stall sometimes at a light.

"the wrong hose going to the wrong thingymajigger" Doesn't help me much, lol

maybe the wrong vaccum hose going to the wrong port or something, its happened to me , i fought a vaccum leak in my 68 for a while, if you put your finger on the hose and it ran better that sounds like a leak somewhere, i just couldnt think of a better way to say it

Like i mean, It idles decent, just when i drove away down the street it seems fine, accelleration's really not a problem, but as soon as i let off the gas and it gets around 2,000rpms or less, it'll either stall completely out, or Drop down to 500rpm approx and barley hold on, sometimes even lower.

I have a 91 Reg Cab Mazda B2200 and then my Bagged Ext B2200, Both have 2.2L's, Manual Trans. I've went back and forth between the 2 and every vacumm lines connected to the correct spot the same as eachother. And the 91 Reg Cab Runs great.

So i think it might be fixed...
