Did compression test this morning 180-170 on all 4 so thats good. But I know that will not tell me if I have a bad valve. I shot some video of motor and exhaust for you to check out.

One other thing that happened, my check engine light has been on since I got it, thought it was due to O2 sensor not being in place (no cat) but when I was doing the compression test I disconnected the distributor and removed the fuse for the EFI. When I hooked it all back up the check engine light was off but once I got out on the road and took off it came back on.

I am trying to see if this does sound like a burnt valve.

 

Honestly, I can't tell from the video the sound quality on this laptop is awful, but I just pulled the plugs and thats how I found my burnt valve. If you do have a burnt valve you should notice a definite miss and even a power loss on these motors (which should be real noticeable haha) or at least I did with mine.

 

It seems to me like it would show up in the compression test which according to the number you gave it didnt.

 

Compression test will show a burnt valve. If it's not sealing it is leaking.... did you get the distributor back in correctly ?

 

Jump the test port and get the codes then look it up and see what it says. I'd start there.
