I needed to fix a crack on my degas bottle (2003 LS V8) and now Im not able to reinstall the bottom hose of the tank. Its not long enough to reach and put the clamp on it. Any ideas on how to install this? Thanks!

i ment jump it in the cold, thanks for the correction

also, as im driving...if I turn on the heat or anything..like a power draw..it starts to mess up worse

yeah I can start it back up...but i thought it needed a batt because it needs jumped when its real cold out. also, it may have a ground issue because when I would have to hump it in the could i would have to use a heat gun to warm up the wires by the batt. then it would turn over...but its...

out of no where i start up the ls and it doenst want to stay running. once its been warmed up a little its better. Im pretty sure i need a new battery...ant ideas

It must be a 3rd cat. I hollowed out the first two coming off the engine and didn't touch the crossover area. I still have a major exhaust obstruction. I'm gonna have to drop the whole system again and hollow it out. I tried a test; started the engine and let it run for just a few...

The pre-cats? I thought there were only two primary cats that bolt right up to the manifold and housed the o2 sensors...one on top and one on the bottom. I definatly removed all of the debris when I hollowed them out, so there's no obstruction there.

Chain of events: This is everything to the last detail 1- Strarted out with one coil starting to misfire and over a period of 3-4 weeks, 2 more coils dropped off and I neglected to replace them because I couldn't afford it at the time. Then rather suddenly, I lost over 50%...

I tried a new filter

I have an 03' LS V8 Ok, I have posted various threads attempting to resolve this problem. It started with a few bad coils. I didn't get around to address the issue until my engine lost over half it's power and couldn't get up to highway speed. Plus really loud noise coming from intake under...

Has anyone attempted to do this? If so, could you explain your results. Also, anyone out there have a plain, custom bent pipe replacing the cats? Results?

Your diagnosis is correct. I removed the upstream o2's and wa-la! POWER! And lots of exhaust noise LOL. Need new cats.

Well, I went ahead and removed to the two upstream O2 sensors from the cats to see if I would regain any power and i sure did! My cats are definatly toast. Now I need to find the cheapest way to resolve the problem. And the quickest. Thank's

I know you did and I appreciate the input. Now that I solved the misfire problem I'm just looking for as much input as possible to confirm that I need new cats and options to address it. If I just remove the cats all together I obviously will have a CEL...that won't bother me but will that...

I had some major misfiring issues and found three bad coils. I have replaced them and I now have no misfire issues. However, one problem remains. I still have a major lack of power and the more throttle I give it, the more power I loose. Also, as I give throttle, the engine is much, much louder...

Thats what I did and got a reading of 5.5 ohms on five of the coils and 6.4 ohms on the other three of them. That has lead me to believe that those three with the higher reading must be the bad coils. Do you think that is accurate?

by the way, I was doing the testing with a standard multi-meter set on ohms/resistance. I really hope this is a good way to test these coils because I can't spend the money to pay the dealership to do it. Any suggestions would be greatly appreciated.

I have 119k miles on it so I cant get it fixed under the warrany deal....man that sucks bad. Last I checked, the limit was 10y 100k miles

I know I have a few bad coils but aside from reading any codes it would have thrown for misfires...can you test the resistance to see if its bad? I've pulled six of them so far and all but two of them, including a new one I just bought, show a resistance of 5.4 to 5.6 and the different ones show...

I got laid off from my job and broke. I cant afford to buy new one s until I get paid from my new job.
