Low idle
I'm having a problem with the idle on my 2004 rx8 stick shift. It's idling very low and eventually shuts off when I'm in neutral. I have to constantly rev up to keep it from turning off when I stop.
Can anyone advise me on how to get back to normal? |
Mine did that with a blown interior fuse, any extra lights on your dash?

^ What!?

Can anyone advise me on how to get back to normal? How many miles on the odometer? When did the last time you did a tune-up? Also, check the status of the fuel pump too. |
I recently replaced the spark plug, wires and coils. I got about 132k miles on it. How do I check the status on the fuel pump... Sorry I'm a newb

Idle problems are never fuel pump related. Unstable or low idle or idle stall is usually one of these: 1: Low compression 2: dirty MAF ($5 can of MAF cleaner at the autoparts store 3: dirty / uncalibrated e-shaft sensor (unplug, wipe it off, replug, reset ECU) 4: Ignition failure You ruled out #4, so it's one of the others. Handle #2 and 3, and if it's still there, take it in for a compression test, your engine is probably failing. |

You are already better off than monchie, who recommended that, since you aren't referring to it as a 'tune up'. He is an idiot, so don't take his suggestions.

Cool thanks. Is there an easy way to clean the throttle body and the Air control valve. <------ how do I locate it?

If you don't know how to locate the throttle body, you probably shouldn't try to clean it, either.
Search for how to clean a throttle body, it's easy to do. I'd explain it, but my RX-8 (and my wife) are awaiting me to take her out to dinner. :) |
Yea I'm not very familiar with all the names but I can do the job if I know exactly the parts I need to work on. Thanks for the info guys
