Followed the great write-ups here to get into the two DIY fixes for P0400 Check Engine codes: vacuum hose replacement and clean EGR tube. It was a PIA, but successfully replaced cracked hoses and cleared the EGR tube.

Here's my problem - I cannot get the lower end of the EGR tube back into the intake hole. The tube is taunt because I couldn't get the rear hex bolt by the oil filter loose. Now, it appears to need to be manipulated and angled a little to slide in and I just cannot achieve the necessary angles????
As you know it's tight between the throttle control beside, hoses and manifold around and above. I am working from the bottom, top and front. Any ideas?

This morning I got up and gave it a fresh go. I removed the oil filter, so I could remove the 5th hex retaining bolt and kept the vacuum end disconnected. This gave me enough movement to get the intake end back into the block and reduced the tension so I could squeeze together and start bolts. It's a PIA from there still. I'll write-up my method, tools and contortions soon.

Feel pretty good about this DIY fix. Too soon to know if it solves the P0400 code or Check Engine - but the EGR tube was definitely clogged. Will post after a couple drives.

Thanks!
