Hello everyone,

I'm contacting all of you in hopes of diagnosing my car; I recently installed new valve cover gaskets and new spark plugs on my Z, my car initial start-up developed a high-pitched whine and dies at around 1000 rpm. I fully reassembled my car and installed the plugs in the correct firing order so I'm very confused as to what this noise could be I think it may be a vacuum leak or something to do with my fuel system but I'm not too sure. Got any suggestions?

Ty I think I found it, the lip of the oil fill ring got caught between my lower and upper plenum, the gap was so large it was most likely causing my noise. Unfortunately though I have yet ANOTHER problem

 

My car keeps doing this:

 

Found problem: unplugged TPS

 

but did you solve the problem
