engine light randomly turns on and Boggs out
 

My 1989 Mazda rx7 n/a will bogg out/ loss of power at about 3000rpm... if i start it the light will instantly turn on but if I turn it off then start it back up it will go off and be ok then at a random time after driving it will come on and will idle but will go very slow please help thanks

Sounds like your OMP is failing and causing limp mode randomly, starting to become very common on s5's

What Light turns on???

+1, was common a while ago but now i'd guess the majority of S5's have had at least 1 OMP fail regardless of mileage on them.

Ok thanks is there anyway to fix it or where can I find the new omp

well, your options are pretty much this

Buy a new OMP and ECU (easily going to cost over a grand or more)
Buy a new OMP and hope the old one didn't fry the ECU (still close to a grand, more if the ECU is fried)
Buy a used OMP and Used ECU and take your chances on how long they will last(maybe $200ish)
Unhook the OMP, put on a block off plate, start premixing your gas and get your ECU rteked (bout $500)
Unhook the OMP, put on a block off plate, start premixing and go full standalone ECU (probably over $1K)
change intake over to carb and carb the engine (close to $1K)
v8 swap it
Sell the car
smash the car
