need help
 

i just got this 89 rx7 n/a everytime i floor it it boggs down any suggestions or where i can start from also my check engine light is on how do i check that and the smog belt is not hooked up could that cause the problem? i also think that the cat or cats are stopped up any suggestions would be appreciated

Read the error code(s) associated with the CEL. Search the forum to find out how to do that. It's a simple process, but you will need to download the factory service manual from one of the links in the 2nd gen FAQ at the top of this forum section to get a list of the codes.

hesitation/bogging, replace your spark plugs, and adjust your tps.

It could also be your fuel filter.

You have a starting point. If you believe the cats are stopped-up, pull them off and see for yourself.
search for checking engine codes, you'll find what you're looking for.

will the belt being off the smog pump do this?

Same thing happens to me sometimes.....

ok i replaced the plugs and checked the check engine light these are the codes i got 9-water thermosensor 20-metering oil pump position sensor 26-metering oil pump stepper motor 33-solenoid port air bypass 34-idle speed control(bac) 40-purge control(auxilary port valve) will any of these cause the bogging down when i floor it? also which ones can i deal with or do i have to fix all this?

anyone i need this car running ?

Sure. It's the Omp code that is your MAIN problem. If it's not working right, then the engine goes into what is euphemistically called LIMP MODE. You MUST fix this problem before the car will run right again.

The water thermo sensor will go into a fail safe mode and just make cold starting more difficult. Fix it as you second project.

I figue you can fix the water thermo sensor by putting it's plug back on. The OMP/?? It's electric so make sure the plugs are connected.

ok i fixed the codes 8 9 and 10
as far as the other ones i havent figured out how do i check the omp sensor and stepper motor and also the port air bypass solenoid and the purge control(auxilary port valve)

ok i found out it has a s4 motor in a s5 car with a s5 computer so the oil metering pump is mechanically controlled and i need a electrically controlled pump metering to plug in to it any one have one?

Check the parts for sale section. Should be able to pick one up pretty easily.

*OR* you could spend 100 bucks and get an Rtek7 ECU to replace yours... Its an easy swap, and would solve your problem without having to have an S4 OMP just hanging around your engine bay.

ok i got a s5 metering pump and now it is throwing a 27 code metering oil pump i dont have it on the block is there something i have to do to the metering oil pump like block anything i just have it plugged in to the harness with a s4 pump on the side of the block

I believe the S5 metering pump has to be operational in order for it to not go into limp mode. There is a shaft that needs to be rotated by the front cover assembly's drive gears... if that doesn't spin, I'm pretty sure it gives out code 27.

Spend 100 bucks. :) Get the Rtek7.

ok thats what i am doing

as far as the other codes what are they and how do i fix them

Well, you "fixed" 8,9,10.... so you still have 33,34 and 40?

Those all appear to be parts of the S5 intake manifold/solenoids... So, ignore them, or get an S5 manifold/intake/etc (all except TB, since you need to control your S4 OMP).

You should take some pics of your engine so we can see what you have.
