Bought 90 rx7 vert. drove it bout 30 miles home anything over 1/4 throttle start missing and backfiring. Replaced fuel injectors, plugs and wires, fuel filter it run little better but same problem! Replaced afm and fuel pump now won't start unless I spray a shot of starting fluid in air intake! Oh and tps checked out good! At my wits end trying to figure this car out! Any ideas?

 

did you get any engine codes on this car?

 

Won't show any codes!

 

shows code 27 and 37

 

Your Electric OMP has bit the dust..and it has(or Could have ) a tendency to damage the ECU if you try to run the car continuously with the car in Limp mode.
Limp mode is the Code 27 that you are getting and makes the car act like **** above 3500 Rpm

 

Well put another omp on it and another ecu! Still going into limp mode! Any ideas?

 

You probably got a crap omp and ecu

 

Well it ran great for about an hour yesterday! Pulling back in at house and it goes back into limp mode! Turn off ignition and let set bout 5 minutes and crank it up again runs perfect for bout 30 minutes then same thing limp mode! Now it shows code 17
