same problems after intake job

ok i redid my intake gaskets, cleaned out everything new plugs new plug wires,new antifreeze, new oil new vacuum lines, new fuel filter new MAF New TPS, new IAC but i still have the same problem with my car, either it wont start and u need to really crank on it, or you need to rev it up with peddle to the floor , it runns at higher RPMS with tons of gas but with die in the lower RPMs. i made 2 videos for you guys of me trying to get it started one outside and one inside the car

https://www.youtube.com/watch?v=ZvdkFRok8pM the outside video

https://www.youtube.com/watch?v=vi0V_ufT61o interior video

outside video doesnt work for me.
is the IAC installed correctly?
is the CEL on and can you read it?
double check the vac lines and plugs.
sounds like the engine has too much fuel and not enough air and is choking out, but its hard to tell w/out being there.

i got it workin

i was told that its getting more air then gas, and thats why its dying

BUMP me baby

Have you tried a fuel pressure test?

Is this more or less common if the tank if nearly full vs nearly empty?

can you verify the map sensor is seeing a 5volt reverence at the connection?

no we have no yet, but the tank has about 6 gallons of gas in it

i dont understand what you meen

I'd suggest testing fuel pressure. If you don't have enough pressure, you can easily stall.

On the map and 5volt reference, he means that you should check the wires on the connector of the map sensor for +5V, one wire should have 5V with the key to the on position.

If it's fuel pressure related, why would it run fine with more throttle, and die at low RPM?

higher the rpms more fuel using. so prob at higher rpms uel pump is able to use the amount of gas it would use normally at lower rpms

check you 2 bar map sensor tot he corresponding voltage at 0.00

Running fine at higher could be a seemingly better. It can run lean and with the rpm up you would notice it less. Also depending on how much higher and correct me on this one as I'm drawing on Bonnsperience, the second stage for the pump could kick in.

B'villes with the L67 have a fuel module that runs the pump at 8volts typically and full voltage when say 3/4-wot.

Also a pump that is leaking down may exhibit the symptoms more at idle. (Personal experience.. 23 lbs barely starts and idles horrible. higher rpm seemed better but very lean)
