Need imput please! Bad missfire and power loss Car sat for about 3 months waiting for a tranny, and i just got her running yesterday. It seemed to be a little sluggish down low (1500-3000 rpm range) but then progressively got worse, to the point of what seemed like spark pull or miss fire under acceleration. Scanner is popping a 1132 and 412 code. Any intel will be great. thanx

If you can, scan it with an OBDII scanner like the dealers use. See if the 02 sensor(s) are switching properly. They will cause exactly the symptoms you describe when they're failing.
If you have the slack in the wires...switch the sensors from side to side and see if the code changes to the other side.

A little rough, i have a 114 lsa so that makes it kinda hard to detect, but its up and down. when i start it it will coast up to about 2200, then slowly drop back down. does the same when im rollin and push the clutch in. Ok i'll try that one later

OK i unplugged both o2's and my idle went back to normal some what. i am now gettin a TPS code as well. could that cause these symptoms as well? the MAP sensor was new out of the box as of may. i really don't see it takin a **** on me that soon just from sitting. my o2 code is gone now.
