Ok, I want you to do this. Pull out a sparkplug and attach the wire to it. Have someone turn the car over, check for spark. Im thinking that your having a problem related to the distribitor/ecu/ignition. I beleive the 1987 is a OBD1 system or a OBD0 (It doesnt matter if its 0 or 1). Im not sure where the 1987 Toyota Supra ecu is located at, but if when your turning your car over and the check engine light is on, you should be able to look at the ecu for a data code. _____ =10 __=1 _______ _______ __ __ __= 23 thats the blinking pattern, it will repeat over and over. Record the code and try to look it up or ask someone with knowledge on the Toyota trouble/error codes, it should lead you to the problem.

"check your cambelt, when was the last time it was replaced? has it snapped?"

The cam belt would cause the valves to stay open, it will make a horrible sound and the engine will shut-off, when you break a cam belt a.k.a. timing belt you will know about it.

If by "replace air flow meter " im guessing your talking about the MAF (Mass air flow sensor), it can be a posibility, If your not pressed for time to get your supra fixed i can try to find a diagnostic flow chart to test the MAF sensor, or you can possibly find one in the Haynes/Chilton manual- Also those manuals usualy have the error codes and what they mean.

Reseting the ecu would not hurt at all, disconect the Negative (-) cable for a period of 30 seconds or more, this will clear all of your Diagnostic Trouble Codes, aka DTC's.

Id like to tell you that you can just change a filter and it would be ok but theres alot of testing to find which of the many possible problems is the Real problem, thats why im in highschool becoming a automotive tech.

something to do with your gear box changing from gear to gear.

Neutral saftey switch, its unlikly but its a possibilty.

'get a piece of wire and jump TE1 & E1 and turn the car over to ignition and count how many times the engine check light flashes'

Thats how some of the older GM's did their check engine lights, ive never done it before, ive never encountered a pre 92 Toyota DTC.
