6 Big black plastic pieces inside my plenum?? - Page 3 - 3000GT/Stealth International Message Center

The fact that it runs differently when warm vs. cold makes me think it might be an FIAV issue ... although it seems unlikely.

Actually could be very likely b/c i did clean throttle body and believe i could have sprayed cleaner in when i just learned the manual warns against that instead says to spray rag and wipe... actually bought whole throttle body including IAC and FIAV when all i thought was wrong w/ my previous was the IAC so i might try taking those off and replacing... Think that's a good way to go??

If you cannot put the pieces back in, I might have a NA plenum laying around. PM me if you need it.

For sure. If you can swap em in that would certainly either fix the problem or eliminate both things from the list of suspects.

I only swapped the black rubber piece that has an electrical connection. I couldn't tell from the diagrams if that was the FIAV (thought it was the metal part) but i'll prolly just look to buy a good throttle body from my local guy. It did help tho b/c car wouldn't start w/o MAF connected and then after switched the black piece it did start. Idk about to go down shore w/ fam so she'll have to wait but thanks for the help...

^^ posted pics of pieces in plenum... also i think someone insinuated that the pieces being out could cause misfire too so even though the pieces are broken i am going to try and 'glue' them in with the same stuff i was told to seal the plenum back up with... but yeah there are the pics of plenum apart for those who are curious

Really cool pics. Thanks for sharing. I've never seen an N/A plenum apart before.

i always wondered why the DOHC N/A had a different intake manifold and why it bolted together. fantastic info!!!
