cel help please

ok ill pick up some heat shrink connectors to make the connections to entend the wiring harness. hey curious the 02 bong upstream is only on one of the 4 pipes of the 4-2-1 manifold does that make a difference? also the distance between the harness for the car to the 02 sensor leaves excess wire gap then if the 02 would had its reach to the middle of the stock cat? does the stock cat have problems when it breaks down to reflect back into the cylinders i dont want to have problems? im my stock flex the 02 bong is messed up i got a rethreader would that fix it, or could they cut out the 02 bong to weld in a new one without cuttng the pipe?

I will only help u more if u go to my thread below yours... and comment on my puppy.

For one thing the upstream 02 should actually be at were all the tubes connect .. if it is only @ one pipe it will be way off about 75% off.....now the rear 02 shouldnt..... now the reason why the upstream 02 is making accurate readings is because it is perfectly fine being hooked up 2 one cyl. As long as the cyl is properly combusting everything.... BUT if one of your cyls is not making good combustion - LEAN-RICH- your computer will never know it....it will always think its running good as long as that one cyl is ok......so basically your setup is totally wrong. This will cost u. your car maybe (i doubt it) have a problem somewere else that has gone unnoticed. But who knows. Mrs. woof woof awaits.

idk how to go to your thread but you have a cute dog by the pic i see online. interesting how you look at the 02 situation on how the reading is 75% off the correct reading being on one tube. what could i develop problem with the way the car has been setup for the last 2 years. it barely uses oil, no more then within factory specs. the idle air ticks but its always been like that, just to cheap to replace already. idk how far to thread in the pcv to make sure i dont damage the pcv allows oil to get sucked into the intake. can an exhaust shop make a small repair to the 02 bong without doing major surgery to my stock flex. well what about the hyundai cats when the break down do they damage the motor? to put the stock back on may be the cheapest and noise reducing thing i can do to my car. but who knows i havent made my mind up yet

Thats my point the 02 would be like your first alert to a cyl running lean or rich.... which are both bad lean being the worst of the 2. As far as the pcv as long as there is no leak its fine.... its not suposed to suck oil. It is probaly okay... it just needs some marginal vacuum. To suck out those vapors from the crank..... Make sure u have that hooked up....u can actually ruin or blow out a gasket doing that so ive heard. but anyways....idle air tick???? ive never heard of that.... u mean valve tick?

and about the cat... how exactly do u think a converter could damage the inside of a engine? the gases push out not in... the worse thing that would happen is that it would clog itself up and just show bad performance and drivability.. no engine damage to worry about.... u should be more worried about those other cyls being ok.... i suggest a compession test on all 4 and throw some seafoam in the intake mani. becuz your engine has probaly some deposits on the valves and wut...not. due tot he wrong fuel air ratio and your not being able to fix itself....

i know my friend has a spec v and its a problem with them that when they break down the platinum breaks down and goes back into the cylinders scratching the walls just dont want that to happen to my car. the pcv is hooked up and i think its ok. well when i looked at the exhause valve openings they were carboned up but i didnt worry about it. ok i thought if you do sea foam you bleed it through the brake booster vaccum line. i thought its a bad thing to due to newer cars because when the "garbage" breaks up its can clogged up in the intake damaging the valves. so if i put it back to stock will the car go back to normal for sure. also why would the head gasket be shot, is there details on how to accurately check the head gasket with the compression tester. so can the the exhaust be patched fixed because a new flex is expensive from my work and through the dealer. good thing the cat is still good and i held on to it.

[g4ebguysite]

idk wut u heard... but that platinum sounds like bullshit....Now if u didnt run your car with a airfilter then maybe not do the seafoam.... trust me you will be fine... people with 200k do it. Dont run it through the brake boost unless u have to...... run it through the pcv valve opening... the key is to put it were it will distrubute through the intake manifold to all cyls evenly at best.

If u would drive to northern IL i would do all this for u if u would buy me dinner. LOL but anyways.

I dont think your head is blown.... im just saying do a compression test to make sure everything is good to go. I mean technicalyl uve been running on bad air fuel ratios this whole time. The computer will do everything it can to fix itself....for example if u pulled the injector from one cyl... it will think its running lean not just on one cyl but all.... and so then it would dumb fuel in the other 3 and make them run as rich as possible most likely.

Theres many things that can happen 1000's.

But a patch... i think u need to weld.

[Izapyou]

id drive to nothern il if you could help me for sure. ill try to use this tap i got from work to see if i can rethread the 02 bong downstream. if not ill have it fixed hopefully cheap. unless adding the cat to my evo fusion setup is cheaper ill do that. i wish i knew someone who could weld would help. idk why hyundai put this idea in my head about an exhaust leak for this code. i wish hyundai would of helped me more considering all the bull ive had with this car and the bad service i got there. if i cant figure this out youd be the biggest help, my hyundai tech friend is always busy and lives kinda far away to help me.

1st of all- I know tons of junkyards around here if we need any sensors.
2nd-I know a muffler shop that does WHOLE exhaust(cat-back) including muffler for like $110 and labor.. they did my gf's car and the work on my accent... i bet for them to do that welding for the cat woul dbe like $20.
that includes the new 02 location. theyd have to do.

Now i cant weld....BUT i can deff help u wire use a schematic and rewire. and help you do any tests on your car you wish.

I am friends with a shop right up the road if we need anymore assistance they also will help me very cheap. for example they did a slave cyl... for $15 for me... and it took them 1 1/2 hours. Now it wont be that cheap for u but it will help if i refer u. But thats only if we run into trouble. they susually help for free. as long as i make a effort.

My point is.... it would be best to help u one on one for the internet is hard to understand in terms of text. if ud make the drive i can help u.

To make it better i bet u can catch some good fish around here....not mention the strip clubs. hehehe....

but anyways... what ever your decision i will be here to help...
Hyundai dealerships suck... they wouldnt even have a mechanic come out to show me were a damn bolt was under the car to help me understand the rear suspension. They ripped me off $155.00 on that one becuz when i finally jacked the car up all it needed was a rubber bushing and they wouldnt take the bolts back. but that was 3 years ago. when i was 16

[g4ebguysite]
