87runner44

Hey guys,
I have a 1987 4runner with a 22re. The other week it was running fine wile driving, then all of a sudden started to idle really rough. I checked the ECU for codes and it threw code 7 and 11. I then replaced the TPS and set it to the right specs, from what i could tell (i used the 4crawler write up). It ran fine for a day, then started to do the same thing. When i rev it and drive it, it seems fine and seems to have power. Above about 2500-3000 rpm the roughness goes away. Its when it idles that it runs really bad. It smells as if the gas isn't burning right. and its running really rich.

so far i've changed
-TPS
-AFM
-cold start injector
-cold start switch
-coolant temp sensor (that sends readings to the ecu)
-i've tried swapping ecu's

I have simply run out of idea's and was wondering if you guys could give me some imput on what could be causing this.I just want my truck running already

Thanks in advance,
Jarett
