code 214, slow acceleration?

Hi,

The code indicates there is an issue with cylinder identification. This could be the result of a few different things.

If you look at the attached pic below, I need to know if the vehicle is still running. I realize you mentioned poor acceleration/rough idle which indicates a misfire to me. But I need to confirm that it still runs to know which test to focus on.

Let me know.

Joe

See pic below.

Hi, yes, engine runs well.

Hi,

That takes me to a test that indicates to clear the code and see if it resets. Here is what to do: Disconnect the battery. With a zip tie, tie the two cables together and allow it to sit for approximately 10 minutes. Connecting the cables drains capacitors, so it's important to do it.

See the attachment below. Next, I need to know if it returns or not. Follow the directions and let me know what happens.

Take care,

Joe

See pic below.

Okay, I'll try that. I disconnected for a couple hours, nothing. I'll be back. Thank you

codes 412 and 538. May be afraid to blow the rods out during flooring accelerator test.

Allan,

Are these new codes? Also, did the 214 return? I need to know. If they are, I have to determine which one is most likely related to the 214 you had originally.

Let me know.

Joe

No, 214 just 411, 412 and 538.

411, 412 are new with koer, first time koer.

Also, I am looking at IAC valve, it reads 11 ohms across the solenoid. The information I can find lists less than 1 ohm as proper, do you know anything about that?

Hi,

The reading you have, 11 ohms, is normal. The only concern is there is a diode in the IAC. You have to make sure you have it connected the right way when checking.

I have a feeling the person that said less than 1 ohm had it hooked up backward.

I attached the directions below. Take a look and confirm you tested it the correct way.

Take care,

Joe

See pic below.

Thank you.

Hi again, did I lose you? I am wonderingif you have anything more onthe411, 412 code and the lag when accelerating from idle?

Hello,

Nope, I'm still here. I thought I lost you. LOL

Take a look at pic 1. It shows the diagnostics for each code. I have attached them for you. Here is what I noticed. One thing in common that both codes have is an issue with the idle air control valve (IAC). However, a faulty IAC isn't the only possibility. They indicate in both to check for contamination.

Additionally, there are two different IAC valves that may have been used. One has a filter on it and is non-serviceable. if that is plugged, maybe it is causing an issue.

Take a look through them and let me know your thoughts. Additionally, at the end of the second set of diagnostics, it indicates what direction to test next, based on findings.

Let me know,

Joe

See pics below.

thanks, I'll be back.

Hi, On testing IAC with ohmmeter, I get 11.4 ohms each way, switching back and forth no difference, is that a shorted diode? an open would be infinite resistance (or close)?

The IAC sounds bad. It isn't an open circuit, but it sounds as though the diode has failed. Have you already tried a new one?

Let me know.

Joe

I have one on the way, none locally. I will let you know as soon as it gets here and on the car, probably around the 8th.

Hi,

Thanks for the update. I will watch for your reply. Let me know if you have questions or if I can help in any way.

Joe

I"ll be back.

Hi,

It has been a few days since I heard from you. Have you had any luck? I don't mean to be a pain. LOL Just interested in knowing.

Take care,

Joe

still waiting on DHL to deliver. seems a little slow, huh?

Hi,

A little. LOL Anytime I have something shipped and it is carried by them, it takes twice as long. I have no idea why. FedEx and UPS are much faster.

Hang in there. Let me know when you get it.

Take care.

Joe

now it's the thirteenth.

Allan,

I have experienced exactly what you are going through with them. LOL I feel your pain and frustration. Hang in there. It may not be as quick, but they will get it to you.

Take care,

Joe

well, it isn't that big a deal really. I don't need the vehicle to get around but it does rub the wrong way when you're told one thing, so you bite then wait because the deal changes on you.

Hi,

I totally understand. Have you received it yet today?

Joe

not yet, supposed to be out for delivery, we'll see soon.

So, I have it on and the lag from idle is better, but light is still on. will check codes again and see what's up with that. maybe disconnect from juice for a while and see if it clears.

Sounds good, let us know what you come up with.
