need help again
 

ok after i deflood my car, my car dont idle at the 1rpm anymore, its like 3/4 to the 1rpm. my battier die during the process so had to jump it, so could it be the battier that is low or something? it feels like the car is gonna die or it feels weak at the 3/4 rpm to the 1rpm

Boyyo, everytime I have disconnected my battery my car acts very crazy, it won't idle well and dies often when it does idle it does so at 700RPM. I hate it running this way but give it 2 days and roughly 100 miles and it will straighten out, I have been told that it is the computer relearning. It will be okay though. I think there is a process of driving patterns to help it learn quicker but I have never gotten them to work for me.

Disconnecting the battery on any car (not just the RX-8) clears the stored fuel trim data among other "learned" behaviors. Over time these will be re-learned and the idle will smooth out.

The difference is more noticable on rotaries than on piston engines


If you want it gone "now!", there is actually a set of specific driving conditions that the ECU is looking for to 'lock in' each parameter. These are all normally hit during normal driving, but some of them require the ECU to see them in more than 1 driving "Session". So go out and drive all over the place, stopping occasionally and turning off the car, pull the key out, start it back up and keep going. You can get everything relearned within a few hours.

The actual parameters were posted somewhere here at some point in the past, but I have no idea where, or what terms to use to search for it.

Thanks RIWWP for being more specific.

people need to start doing this or i will just begin closing threads that say "help" or otehr such crap in the title.

alright cool thx

its been a while now, and its still not sitting at the 1rpm, when its cold yea it sit over 1rpm but when its all warm up its under 1rpm? so what now

The engine is supposed to idle at 800-850 RPM, not 1,000rpm. Where is it actually idling at?

Mine idles between 750 and 850. It shouldn't be idling at exactly 1000 that is kinda high.

mine say around 700-800, it kinda shake abit, at first before i deflood my engine the car was idling at 1rpm, got no shake or anything, but after i deflood it started gettin this problem, have a 2004 got 23K mileage

mine shakes.. my friends shakes. mine is aftermarket, hers isn't but the idle the same.
