Where is the MAF sensor on this car?

I tried cleaning the throttle butterfly today with some carb cleaner and it hasn't really done much, the gas pedal feels better and I think it idles better now. However I think that's something that needed to be done anyway, the problem is still exactly the same but if I put it in third and hit the gas it shudders at about 40 and won't won't go any faster. Also tried disconnecting the TPS and driving it, didn't work.
