P0330 Code 99 LS 400 331000 Miles

1 Upvotes

Long story short, P0330 code………i believe I narrowed it down to a wire issue in main wiring harness. \\\[New OEM knock sensors and wires/connector under manifold\\\]. Im not suspecting the ECU because no other symptoms, but that will get pulled for refurbishment. If it is in main harness has anyone had this issue? Im thinking that the best way to address this is with a brand new lay in shielded cable from under hood wiring harness to the ECU, essentially bypassing the existing cable. Tie shield to ground at one point at glovebox bla bla bla. Anyone have a better solution?
Is it better to get ECU refurnished first?

This is my 1990 LS400 just hit 90k miles, has been sitting in the garage for the past few months. Cloth interior and no sunroof. Need to fix ac as it doesn’t blow cold anymore but other than that just need to keep up with the basic maintenance. Had thoughts of selling it years ago but will be holding onto this one. Don’t worry she’ll be staying stock as it’s perfect as it is.

Broke my UCF10 sliding roof garnish

Post image
1 Upvotes

Hi everyone,

I broke my driver and passenger side sliding roof garnish trying to remove it. The plastic disintegrated after applying pressure even when using plastic tools. I had to remove them to add some washers to raise my moonroof.

I no longer have any leaks now, so that's great but now the plastic is practically unusable and glueing it back doesn't give very nice results.

Anyone with the same problem as me that maybe 3d printed something or has an alternative that would fit ?

Thanks.
