IMRC cable broke?

[SHOZ123]

If you never hit the opening rpm it will not set a code.

The code is triggered by a micro switch in the IRMC box. When the cable is out, even a 1/4", the switch is sees this. If the cable does not retract fully it sees this too. My problems were usually a frayed cable that would not let the cable fully retract. But the IRM secondaries were still operating because the cable had not broken yet.

Either the cable is broke or the gears in side the box are if the cable is not working at all. Pay no attention to whether it is #1 or #2.

What size zip tie would any of you recommend for wiring the secondaries open? Would a 5 mm zip tie hold it or would I need to double up on smaller ones?

if you are a fan of preventitive overkill..go to Home Depot in the Garden Center they have zip ties that remind me of the police ones. They are in PVC tubes by the fertilizer bags. They are nice and stout

If you do clean the LIM just take the secondary plates out. Easy to do.

I found out (by accident) there is an easier way to wire them open. I just don't know how permanent it is going to be. Of the two spring things holding tension on the secondaries, I dropped the nut on the right one. Off to the hardware store. The replacement nut was about twice as thick and, to my surprise, held the spring in place with no cable ties needed. The nut cost me a quarter and I will do the other one when I get a chance. Just letting you guys know that there IS and easier way to wire open the secondaries!

I used a peice of coat hanger to wire mine open, then added a second for redundancy. I only ran it this way for about two weeks while I had the IMRC off for repair, but never had a problem with them. Using coat hanger wire actually made wiring them open easier because I used one end of the wire as a hook to catch the actuator arm and pull it open. Didn't have to touch the throttle body to do this.

Would like to say hello to all..New IMRC box,butterfies are stuck open,could some one tell me if i can clean them with out taking down top end,if so //how??(i have had problems ,emmision inspection sticker disconnect ,reset code ,worried after enough drive cycles passing for inspection in nc.. ,had to take off road ,want to get back out there with the rest of the sho,s in the world.. info appreciated very much ...Thanks...

In order to pass NC inspection when my IRMC went south, [engaged all the time the motor was running]. I wired it open, unplugged IRMC, cleared codes & passed inspection with flying colors. As long as no codes are showing you should be able to pass inspection.

Thanks 4 the info..I think my butterflies are stuck open .I suppose, i disconnect IMRC and run the vehicle for a 75-100 mile cycle ,see if code pops up and all pcm functions are complete for emmisions for inspections at station.Sounds like ,i will have to tear down top end to clean butterflies ??

Well I wired open the secondaries and unplugged the connections and the car ran fine (stumbly idle for a bit)...

Well a mechanic said that it causes the light to go on, and the car was having trouble starting it. So he let it shut (cut the zip ties)...

Does this sound right?

How is everyone else able to do it, but when I did it, it screwed up the car somehow...

I think the mechanic isn't an "expert" like he says...

 

[stephen newberg]

My guess would be he is not much of an expert. You might get some stumbling at first as the system relearns and some slightly harder starting in cold weather. Otherwise, there is not effect. The SES light can be cleared by unplugging the battery after all the other wire open and unplugging the IMRC is done. It will not reappear due to the runners again after ou do that.

Yes the PCM needs to relearn what it takes to get the the idle and cold start fuel right.

Clear the PCM and start over, it doesn't take long.

 

[mike96]

thanks to all the responses ,I did buy a new imrc box,i guess ,i will do as previously stated & in the near future tear the top end down & clean the butterflies and get back that small bottom end back again...

 

[mike96]

code came back>>& ses light

disconnected battery ,unpluged imrc box, DIDNOT wire seconderys open...(they are stuck open intake manifold runners)(code1518)i thought it was.After 20 miles computer learns itself the light & code comes back on ???Is this because i did not wire open ///???: something that is already stuck open?? I know it is repeated info ,but no time to clean lim ,right now..After dmv inspection ,then i can find the time...

 

[SHOZ123]

For some reason it may take a couple of code clearings with the IRMC box disconnected for the code to stay off. And FWIW the secondaries are not really stuck open, it is more like they are not fully closed. And that may bot be true either as if the cable hangs up just a bit it will set that code.

 

[mike96]

Thanks 4 the info .I will clear the code again,&see what happens.I just want to get past the inspection and then spend time on lim cleaning..

 

[mike96]

New code 0401- Exhaust Gas Recirculation Flow Insufficient Detected ..What is scoop on that??
