91 rs v6
 

i have a question about my v6 camaro
it runs good, smooth most of the time.
the other day i was driving out of town which i have a few times but its in the mountains so im pullin a hill for a good 30 mins.

about half way up the car downshifts and my rpms go up but i lose power and blowin all kinds of black smoke out the exhaust. i pull over, dont turn the car off. no misfires nothing seems wrong, i get back in the car and it gets me there just fine the rest of the way. since then when i start the car i smell fuel and when the motors cold it seems to mis fire or sputter when moving from a stop or giving it more gas.

bad regulator? i have pulled the vaccumm hose off it, not spilling fuel out?

anyone have any idea or maybe have had this problem?

Hook up a fuel pressure gauge, check for proper pressure & bleed down rate.
Make sure the vacuum hose to the map sensor is good.

ill have to check the pressure when i get a testor. the hoses are good. i forgot to mention as well. i have my egr blocked off. i have a spectre air filter and e3 plugs. there was a connection on the old air intake canister which is not there anymore and the connection isnt plugged into anything at the moment. would any of this have anything to do with it???

That sounds like the inlet air temp sensor, yes it is important.
