update: all the below still remains but installed and calibrated wideband setup and found that air fuel ration is sitting at 10.7 at idle , which explains the super rich smell .. but whats the cause , i recently replaced the afm with a rebuilt unit, cap rotor ,plugs are all new , and i still have all the codes 2nd gen 3sgte swap into a 94 gt ,tweak did the harness will idle all day smoothly , timing is at 10 degrees , but as soon as you touch the throotle it falls on its face and if you slowly throttle it up it runs out to about 4 grand and actls like its cutting fuel , ,,, its got 6 codes showing , 22 24 32 35 41 47 pretty much every main engine sensor on it , whats the deal ,thanks This post has been edited by pxcr440: Jun 9, 2010 - 8:12 PM |

i didnt get the codes, but my supra behaved exactly the same way when one of the fuel lines in the tank broke. the fuel pressure dropped as soon as i would touch the throttle. try that?

Engine Coolant Temperature Sensor signal.
Intake Air Temperature Sensor signal Air Flow Meter signal. HAC Sensor signal Throttle Position Sensor signal. Cant find a 47. The fuel issues is most likely the AFM. I had issues with my afm, so I swapped it out and no more issues. -------------------- 98 Celica gt red- totaled deer

Check the wring to your safc2. Make sure all the connections are soldered in and not crimped. Then make sure the safc is correctly set to Flap, 2in/2out, 4cly, throttle UP. Then reset the ecu by pulling the efi fuse (or disconnect the battery) for a few min, and check back to see what codes come back once the car has been running for a while. -------------------- 15PSI - 30MPG - Megasquirt Tuned
