LOL - Your right ! I listen ! Maybe to good. Well, troubleshooting those codes seemed pretty basic to me - fairly simple to find the problem without throwing parts at it. The only point that Bluegrass mentioned about those codes that I don't get is that they truly mean your running rich. He mentioned that in one of his posts in the past.

I can't find any supporting data. If that is indeed true , then that would bring the O2's into the picture. Because as you know, running rich will foul the O2 sensors quickly and if that's the case, your sure to generate an O2 fault code.

Maybe I misunderstood that post from Bluegrass , but I read it over a few times with the same conclusion. That IS what the man was saying IMO.

 

Jim, the OP is not getting any codes - just a high idle.

A high idle without a CEL means that whatever extra air is getting in there is probably metered - it's coming in through the air cleaner and past the MAF. This is caused by a bad IAC (stuck too far open?) or a sticky throttle plate, etc. The system compensates for the extra air by throwing extra fuel in, raising the idle and keeping the mixture correct.

If he had a vacuum leak, that's a different story. That air is not metered and it confuses the hell out of the system, likely throwing a CEL. The O2's detect excessive lean, the PCM can only correct with more fuel so far till it hits the limits because of the low flow readings from the MAF.

The OP could have a vacuum leak minor enough where it won't unbalance it enough to throw a lean CEL, but if it's idling at 1800, that would certainly be a severe enough leak to trip a CEL.

Make sense?

 

Oh , your right!! MY bad - I must have confused him with another. :o

I'm not sure I'm going for his story - BUT -

The OP should be able to locate the problem with all the info in this thread. IF he decides to listen to any of it . I think he wants to point to a part and hope that one of us will say - Yeah , replace that!!

 

hey im on TT as Motogoalie, I bet i have more posts than you


who are you over there?


(and it depends on the OP and the retardation level involved as to how nice I am to people....just like a throttle body and fuel injector setup. My internal CPU compensates for stupidity intake by increasing the level of irritability and red *** in the reply)

 

Okay, I can do that - replace the IAC. However, if the throttle plate is sticking due to crud or misalignment, that won't fix it.

 

What gets me - If he is idling @ 1800 rpms, how the hell is he even driving it

You would be on the brake pedal more the fuel pedal..

 

Code or no code, there is extra air getting in.
That's the only way a motor responds.
How it's happening has to be found.
You bet that I couldn't use my truck with such an issue because I have a low stall diesel converter that I even have to brake when in 4 wheel low,it pulls so hard unless the motor is fully warmed and back to normal idle rpm, even then it will creep pretty good.
If the air is drawn thru the MAF then it is metering it and adding fuel so there would be no code same as normal.
An air leak between the MAF and throttle body would be unmetered and shift the fuel tables and cause a code if bad enough same as a leak after the TB.
Are you sure your throttle cable, linkaged, pedal etc are not causing a problem?
There are mounting bolts, gaskets, hoses etc that all have to be looked at otherwise.

 

I have 8,357 post on TT

your at 1700 not too close to me.

I assume this is you. I am Gene426 on TT (Motocross is my Hobbie)



Yes I was hoping someone would point at a part and say "That's it..."
Hey I can hope cant I?
I thought this was a forum to ask questions....

 

Its standard and it doesnt do it all the time......

 

Yea, but

Well, that could get expensive that way . I guess if you pointed to all gaskets and vacuum lines/hoses you bound to get the right one sooner or later.

Your problem isn't just a part or sensor that needs replaced. It's usually not that easy. The best anyone can do to help is give an area to troubleshoot and help you with servicing parts/sensors that tend to get dirty or wear out over time.

I think if you were to visit an auto parts supplier in your area and purchase a Haynes or Chilton's Service manual and look up what everyone has mentioned here , it would be much easier.

Good Luck.

BTW - I miss my CR500 Specially when I see my old Moto3 and High Point boots on the shelf out in the shop.

 

Well, I'm pointing at the IAC. As with anything else, it may or may not be "IT" but it's where I'd start. I would not replace it without trying to clean it and the throttle body and associated passages first. Proper troubleshooting of just about any issue requires analysis of all symptoms and trying things that don't cost money first.

 

He already replaced it (page 1 arrow 1) - pay attention mister

 

Okie dokey - to me, that now points to a throttle issue - agree?

 

Yea , he said it doesn't happen all the time. I think Bluegrass mentioned the throttle cable. It could be frayed/kinked somewhere. The throttle plate could be hanging and need cleaning.

To be @ 1800 RPM's just some of the time doesn't really sound like a vac leak to me. He would be having problems all of the time with a leak that bad.

 

Why would it be such a hard task to remove the air duct hose from the throttle body and disconnect the throttle cable to see if there is a binding problem with the throttle plate operation?
It may even be the cruise control cable causeing this.
Look at it! It's probably stareing you in the face!
If you can't translate advice into action, you will never fix it.
