Check engine light on - please help
Hi, I had an issue with the radiator of my 03 rx8...but its fixed
after i reinstalled i try to start without the air filter kit to check for any leak from radiator (the engine didn't start at first time and I did not insist ).
- reinstalled the air filter kit, the car start with no problems but the checking engine light come on.
please can you help me
thank you

I see you are in eastern Africa, so there may be limitations on your resources available, still, we can't help without the code:

Questions we can't answer:
'My Check Engine Light is on, what is wrong type' questions. Any question related to a CEL is worthless unless you list your car type and the PXXXX CEL code. Without both pieces of information you won't get a straight answer. Listing your modifications and the time line between your last mod(s) and the new CEL helps too. We also have a list of all CEL codes here: RX-8 Technical Info (CEL codes, PCM pin list, collision guide) - RX8Club.com If you do a Google search on the site for your CEL code, you will find prior posts and threads of people that have had it, and what they did to resolve it.

What does the Check Engine Light (CEL) Mean?:
The Check Engine Light, also known as a CEL or MIL, is a light that is lit up on the dash by the ECU when it detects something wrong. It is NOT comprehensive about everything that could go wrong. In fact, your car could be on fire and it wouldn't know. The ECU only monitors EMISSIONS related items, due to the US laws that were enacted in the 1990s regarding emissions and OBD2 compliance. There is a quiet push going on as of this edit to further expand the items monitored, which may result in an "OBD3" in the next 10-15 years. Also, note that it monitors far more than "the engine", for example the ECU knows if your gas cap is loose, and will throw a CEL code for a fuel system EVAP leak.
If your CEL lights up, you can clear it a few different ways:
1) Disconnect the battery without reading the code to see what is wrong. This also clears your fuel trims, audio head unit presets, DSC/TCS learned parameters, and your car may idle roughly for the next few drive cycles.
2) Go to an auto-parts store that will read the code for you for free, and then will clear it for you if you wish
3) Buy a code reader for less than a diagnostics fee at a shop, read and clear it yourself, and read all future codes on all your cars for free
4) Buy a bluetooth OBD2 dongle and pair it with your smartphone or tablet and an OBD2 app
5) Go to a shop and pay their one time diagnostic's charge to get the code for you
6) Go to a dealer and pay their even higher one time diagnostics charge to get the code, and then charge you even more for fixing it.
When the CEL lights up, there will be ONE OR MORE of these codes stored in the ECU. Some hardware failures will 'throw' more than 1 code:
