MX-3.com

Since i bought my MX-3 it has always had a low car idle. We adjusted the throttle and the car usually rests in park at 2000 rpms and then stays at 1000 after it's put into gear for a while, and then after about ten minutes the idle gets lower and lower and eventually as low as even 100! at times. What do i do? that i haven't already? is it the ECU?

i have the same damn problem.. someone help

I have had this problem before. It could be a number of things. It could be the distributor. God only knows how many of us have had a problem with that. It could be your spark plugs or your wire set or it could be your throttle plate. I had that problem once I replaced my distributor and I could not fix the damn thing. I worked on it for a week. Finally someone suggested reseting the ecm. You do that by taking the btu fuse out and holding the brake in for 5 seconds. Immediatly my car went to 3000 RPMs. I lowered it down and it worked great. I would try that first. It couldn't hurt. The btu fuse is under the hood. With all the other big fuses. If that doesn't work. Look at the above.

Hey ADB98,<P>That sounds like it might work cuz i've done EVERYTHING you can think of on my computer and nuthin works. So i think this will i'm gonna try it and then i'll let yall know if it works

about doing the btu reboot thing, do i do this while the car is running, or while it is off and according to my manual it says i have a btn switch> is this the same thing or is it different? if so can you send me a diagram or something via icq or e-mail? thanks man.

I tried to reset it with car on and off, and it didn't do anything. I think i need some exact directions on how to do it

i just got my wire set today.. the low idle is gone!!!!

SORRY I WAS WRONG. IT DIDNT FIX THE PROBLEM..<BR>I LOVE MY STUPID CAR

I just reset me ecu today and i drove it around for a good 1/2 hour and idle still stayed at 1, it worked! woohoo! Thanks alot guys

I'm having a low idle problem to. I have done everything that you guys had just mention. The only thing I found wrong with the car is her ICV (idle control valve) is sticking. I will be replacing it soon, but it's $300. If that helps I will tell you guys. Look in to it might help. [img]shrug.gif"%20border="0[/img]

I was wrong it fixed it for a bit, but now it's fucked up again i dunno what to do!

LOL.. i had the same thing.. i bought a disty...fixed the problem for 3 days... got wires..fixed the problem for 30 minutes.. but now. my car is running prefect.. its fast smoother... get wires... so many people were telling me this along time ago.. i finally listend and now im happy see

hey, ive been around garage quit a bit. and one day an old 323 or 626(not sure, it was a while ago) but it hade the same problem. The car ran great except it idle was really low at 100rpm. So the machinic took off all the air filter equiment so you could see the butterfly valve, started it up and sprayed some wd40 in there. The problem was that thers is a hole that lets the air in, when the valve was closed was full of dirt. So just take an old toothbush and clean it out.<P>hope it helps

i think i gonna need more info then, that can you gimme some details so i can try it right now?
