4age Smallport Low Topend power.

AFM? This engine just gets stranger and stranger, I've never seen an AFM smallport before....bigport yes (not ADM though, although can't remember what AW11s are), smallport no. Or maybe you were referring to the air-temp sensor, not the air-flow meter.

Photos of the engine could go a long way to clearing up the confusion here

AIR/ FUEL MIXTURE sorry bro. (Least i think thats what its called.) Not used to the forum chat. Yea i got my power back. A flange near the cat. The dizzy was sweet. All runs well now. Thank everyone for you help. Yea i know for sure its a smallport and no tvis on the plenum. Dw its not a blue top. i have one of them sitting around. Plus another red top and 2 ze's.

AFM traditionally (at least as far as older Toyotas are concerned) stands for Air Flow Meter, most often a flap-style sensor in the intake piping just after the airbox, it's about the size of your fist and hard to miss. No ADM 4AGE had air-flow meters, they all had MAP (Manifold Absolute Pressure) sensors instead (silvertop 20valves do though). The little sensor (looks like a little antenna/Christmas tree) that plugs into the airbox is the intake air temperature sensor, which (along with the AFM/MAP and TPS (Throttle Position Sensor)) determine exactly how much air is entering the engine, and then the ECU tells the injectors how much to inject.

So technically it has got something to do with air/fuel mixture (to be safe, call it AFR for air/fuel ratio), but it's not an AFM.
