You may have a vacuum leak aswell. It could be fuel pump but this will make it hunt and drive like a pig. Best of diagnoses reader see what sensors a.d switches are doing!

You tee into the fuel line. But is it blowing black smoke mAnifold may be cracked.

no smoke. 63kmiles runs smooth. with soft acceleration it will get up to 70mph but it wont go faster. makes me feel like its not getting enough fuel... maybe transmission related? i love this car but hope its not gonna cost a fortune to remedy.
