Trouble Code 32?

[sasquatch094]

:iq:Hey whats going on guys, yes Another question for you guys. Popped a 32 trouble code a while ago and never got around to fixing it. im going on a 4 hour trip next week and well i needa get that thing cleared. I called murrays said it was an EGR malfunction or something to that sort. (95 Tahoe 350).. Do these trucks have EGR's and if so where are they located at? anyone ever replace or do something with this stupid thing??:cuss: thanks guys.. Hey, and what the hell does this EGR thing do?? thanks

exhaust gas recirculation, reburns exhaust and lower emissions, ugh!!! yee u have one, probable lots of carbon buildup on it.

yea i found it, its like behind the throttle body. Do you think i could just clean it out with like brake cleaner or something, bucz those are kinda pricy, and if thats all it does is lower emissions, then screw it, i wont replace it. now if it somehow gets better mpgs then ill consider, getting 12 isnt cutting it.. lol.. or should i just go to the junkyard and find a 350 and just pocket-it out.. i mean i guess one of those would work..

I have heard or people taking the hose off it while running and putting the hose in a cup of water and letting it slowly sip the water and its supposed to break up what ever is clogging it

 

[mygreen98]

sure, take it off, clean it down with carb cleaner, or brake cleaner. also clean insde the manifold area where the pintle of the egr meets the base of the egr. i would also spray some wd-40 or equivalent on the egr shaft, it needs to move freely, it may be sticking due to carbon, good luck.

ehh alrite alrite, ill give that try.. does this do anything to mpgs or probably not right? either way if i get it fixed or not im not buying a new one.. lol..

 

[mygreen98]

once its cleaned you should get atleast 30mpg. lol. a poorly functioning egr can cause the vehicle to run subpar, thus reducing gas miliage. that being said 30 mpg is a bit much on my calculations, 29.5 mpg sounds more like it. good luck. post your findings.

You need the EGR valve so that your ECU can properly manage your engine, otherwise it will run like crap. Any error codes can cause your computer to run in an open loop, causing engine management problems.

EGR valves do go, it is a fairly common thing, just like O2 sensors go. I replaced mine early on this year... but I don't remember it being that expensive. Autozone shows them being in the $50 - $70 range, but I swear I don't remember paying that much. Maybe I got a remanufactured on? Doubt it. Wierd. It is a pretty common part considering all the TBI 350's had them I believe. Just go to the junkyard and yank one.

your kidding about the 29.5 mpgs right? lol.. im getting 12 to be exact.. but hm maybe i needa get one of those bad boys then, damnit, one more thing i have to do on the list.. hehe..

you can double that 30mpg by letting the hose sip a full can of beer. it only lasts for a few hours though, and then your truck will run like crap tomorrow. but then it will go away.

 

[mygreen98]

are you talkin about lite beer, or ale? i believe the ale burns more elliciently

 

[bsamoul]

Do you have a pic of where the valve is located and what you clean?

 

[sasquatch094]

yea lemme go outside.. one sec..... right behind the aircleaner. but this is for a 95, im not sure what year yours is. 96 and above may MAY be different.

 

[mygreen98]

if you have tbi its in the rear, if you have vortec with cfi its in the front.

solves the question, but still havnt done anything to that thing, and my light keeps going on after 10 min of highway driving only, i can drive all day in the city and nothing, only highway..
