Damn KA Bogging

Just save the video file (mov, wmv, whatever) to your hard drive then upload it to photobucket. But Kodak should have a way to share videos hosted on their site..

Well twofortyrida,

My car is tentatively fixed at this point.

1. recharged the air filter/threw in the fuel injector cleaner/checked MAFS for cleanliness

2. cleaned IACV with Carb Cleaner/replaced fuel filter/tested fuel injectors

Seems to run fine now though I am not convinced it's fixed completely. Many of the accounts of issues I have come across similar to this say that it stops bogging/shutting off for a few days after the IACV is cleaned and then the issue returns so I will post again and let you know how it is going and see how your issue is going.

Funny thing is, I went to test drive it after we got everything put back together and my f-ing lowbeams weren't working...so I'm gonna be hunting new gremlins til the bogging rears its ugly head again.

On a side note:

My friend showed me a nifty trick to check and see if your fuel injectors are working right. You take a longish piece of metal (we used an 10inch drill bit) and touch one end to the metal part over the injector and put your ear up to the other end. You will here a rapid ticking if it is working properly. He told me that if one isn't working properly then then it will sound alot different.

Big thanks to everyone, Mello especially, who has responded so far. I have learned alot.

Mello, I am not from NV, I just happened across that site.

Thanks guys I'm gonna try to get that clip on here today. The car bogs but it hasnt done the stoplight bogging in a while, but I havent drivin it on any decent length trip then stopped.

My computer doesn't have kodak easy share but my roomates does. He's asleep so Ill get the clip on Wednesday or Thursday.

Well I thought it was fixed but I fired it up and here comes the sporadic idling again. I'm starting to think its my MAFS wiring. We shall see...

[ladiesman8527]

have u checked your TPS?

[plinkus]

No, I don't have a multimeter so I am thinking it might be time for a trip to the shop

[ladiesman8527]

a multimeter is what? $20? just get one. its worth its weight in gold.

[plinkus]

Holy crap...

I didn't realize they were so cheap. Can you believe I am an electronics technician?

[twofortyrida1388]

My ass needs to pick one up as well.

[twofortyrida1388]

Hey mello when I try to save the clip on my harddrive it says saving pic and only uploads pic.

[smily_vigor]

Any lastest news with this issue. It's still happening to me (when I can actually get my car started) The wire with the buldge that might be shorting, is it the wire comming directly off of the knock sensor?

[plinkus]

Mine is still goofing some too... I haven't had time to get a multimeter or anything like that. I am thinking its time for a trip to the shop just to save myseld the time and hassle. I will post up what the results are when I get it back.

[twofortyrida1388]

My car hasnt done the bogging after light in a while but if I floor it in neutral it still takes it until 4k to really open up.

Check/change your injector O rings for leaks FTW clean/replace the injectors if nessicary. my car used to bogg, doing this fixed it...

also be easy on the K&N filter oil stuff.. too much of that can piss off the MAF a bit.. after doing the above if you wanna take more shots in the dark.. theres electrical plug cleaner stuff for junk like your MAF plug and other random stuff

goodluck lemme know if this works

[twofortyrida1388]

Thanks. Lately I have been getting injector advice so I will have to check them out.

[twofortyrida1388]

What would be the best suggested method of cleaning injectors and what cleaner to use?

[MELLO*SOS]

I think most of that pour-in-tank injector cleaner is a joke. To do it "right" pull the injectors and send them to an injector cleaning service, like Deatschwerks. It's like $15 per injector, they'll come back as good as new rebuilt with new o-rings, filter basket, etc.

[twofortyrida1388]

Thanks mello88. That is awesome. Much cheaper than getting new injectors.

It sounds like you are getting air in after the maf. Intake Mani gaskets, and piping between maf and T/B. What is the Vacum @ Idle?

I had the same problem...it did infact turn out to be air getting in after the MAF. One of the off shoots of the plastic intake piping was extremely loose (near the passenger side of the radiator) tightend that up and problem dissapeared for now

[twofortyrida1388]

I dont have the plastic intake anymore. The only place I could be getting air after the MAF is the intake mani gasket. I doubt it. Like someone said Heat=Expansion but idle is fine after it warms up it only bogs when floored. If I ease on the pedal to redline it is fine.

Yeah they do awesome work with a quick turn around too. I had them do my RB injectors, they came back looking new... They'll also number each injector and give you a report on the final flow for each one. There is a deal for Zilvia members for free return shipping and free upgrade to the "dynamic service", it should end up like $15 each with that deal. GL

Edit 2: You may be getting the bog after it's warm due to a couple reasons. But one thing I'd check right away is the temp sensor and/or the wiring going to it. I believe I have a short in mine somewhere, if my KA is warmed up and idling I can fiddle with the ECT wiring and get the idle rpm to change...

Edit 3: Okay to help you find your intake leak... You should either buy, or build, one of these things:



Then clamp that in place of your air filter (if you have a MAF adapter and cone filter -- If you have a stock style airbox take off the MAF and clamp this to the intake tube), and hook your air compressor up to it. Set the compressor regulator to like 5 or 10psi. That'll be more than enough pressure to hear where the air is leaking from (probably enough to blow off some loose fittings too, lol). Be sure to unhook and plug off the PCV setup, and any other crap like that (the charcoal canister for instance). You can use a little spray bottle with some soapy water to squirt around the hose connections, gaskets, etc..

[twofortyrida1388]

Damn thats some cool shit. So being on Zilvia I can get free return shipping and get the dynamic upgrade too? Thats insane.

[MELLO*SOS]

Yep. Check out this thread: http://www.zilvia.net/f/showthread.p...t=deatschwerks

GL dude.

[twofortyrida1388]

Thats great, can't wait to get mine done.

[BigVinnie]

Dude did you ever check to see if you had a bad belt fan clutch assembly. If the clutch on the fan doesn't disengage the idle fluctuates really bad, and sometimes can cause the engine to shut off. It can also cause bogging issues.

[240silvia]

He doesn't have the clutch fan on the car.....

Next.... lol.

Sterling this is the longest problem I've ever seen.

[MELLO*SOS]

Diagnosing bogging is fun! Here is my old thread about code 34 bogging from 3000 to 5000:

LOL! CHARLES! Whats up dude. You know how bad my shit can be. I should be getting struts very soon so I can go to your place and you can help a brother out.

You bought another bike??

[twofortyrida1388]

I read your code 34 thread and got some ideas but my bogs(only WOT) idle to 4k(in neutral) then really really screams and opens up after 4k.

[Tech12]

have you checked your tps yet?
