I have recently bought an 87 supra, i have found that the headlights do not work properly, when i turn the switch the headlight pop up, but the lights dont work,unless i turn the high beams on, fuses all check out and i replaced the whole switch, not sure what to do now. Second problem is i had just gone through and replaced plugs and plug wires, after i did that the car tops out at about 30mph before the engine stalls out, under the hood i can crack open the throttle and rev it up to about 2,000 rpm before it stalls out, even if i keep opening the throttle the engine wont respond until the rpms drop back below 1000,if I unhook the tps it works fine just idles high but i replaced the tps sensor and checked out the intake hose, all ok, also cleaned the throtle body and replaced the gasket and checked out vaccum lines, all appear to be hooked up

Is your engine light on? If so pull the codes. The reving thing sounds like a possible AFM problem
