Dude, I Have exactly the same problem.

I bought the 90 model mazda B2200 with no options assuming it would get way better gas than my bigger truck. Well, It wouldn't start when I first got it and the guy told me it sat for 4 years. Well, the fuel lines were cloged and the strainer in the fuel tank wouldn't even pass air so I just took it off and installed a big fuel filter under the hood. Well, since then I broke 2 arms off of the mechanical fuel pump and bought an electric one from autozone. Well back to the problem. If I leave it at low idle, it idles fine until i drive it. Then when I let off the gas real fast or stop, it dies unless i give it gas, (which is hard to press the brake, gas and clutch at the same time). It Accelerates real well if you don't give it full throutle, but at full throtle, it kinda has no power at all.

I have tried to set the timing and adjust the idle higher but it still doesn't work right. I don't know how to fix it because I have never worked on an electrically controled carberator with tons of vacuume lines and lots of little electric vacumme control vaves. I did clean the needle and seat because it was flooding out at first. I also belive that it runs really rich because it only almost gets 16 miles per gallon which sucks for a 4 banger.

I thought about the computer or the idle air controle valve (if it has one). I also belive it could be one of those electrice things in the carberator, (don't know their proper names.)

If anyone out there has had these problems, It looks like we both need help. Im fixing to park it on the side of the street with the keys and singed title in it. (well not yet anyway)
