Hello looking for any help im ki d of stumped and don't want to go into every detail here. Ill add a video and it mostlyshows scan tool data and how my engine shakes after revving it. This also happens when comming to a stop and my short term will even drop to 3% rich but since ive adjusted my throttle plate to stop sticking i've noticed less idle fluctuation and a good base idle and ive come to realize it could be my throttle body because it's 70mm paired with a sku k 2 i take but that would mean its been since i got the car months ago. Buy my engine idles rough and I don't thik that's the whole story. Stft increases to 35+ lean on the scan tool when accelerating under load but will drop to 0 when letting off the gas to cruise. Any help is much appreciated sorry for the rambling 🙏🙏 was going to add a video of my engine bay but only one video

Continuing the last post for a vid of tge engine, I don't know if I mentioned but its a p0170 fuel bank 1 code and p0171 running lean code after 2 hours of relearning. I did replace my Intake manifold gasket and check for vacuum leaks but no luck. A

I just swapped the engine and it was bogging but I could get it to rev up but now I can’t get it to rev up at all without bogging.

snapped a valve cover bolt and tried extracting but now it won’t sit properly in place and valve cover isn’t seated properly. (i did clean/ catch all the metal shavings) Still runs good just hate how the bolt doesn’t seat all the way. Is it still fixable or should i just replace the head ?

Hey guys, I’m looking to buy a Del Sol and I found a clean one, no rust and no abuse. The only thing is that when it is pushed, after an hour approximately, the engine does this. Neither I or the owner know the cause of this. Has anyone seen anything like this?

Edit: I forgot to mention that it’s a ‘93 D16Z6
