[figgie]

What is your intake pressure reading at the time of stall.
Fuel pressure.

 

[CarlosPTR210]

like what rpm is it stalling at: at 4500 and drop to 2500 then 4500 and drop again.

What is your intake pressure reading at the time of stall: +-15 psi

Fuel pressure: at idle 30psi with vacuum, when stalling I don't know

What do you think?

Did you ever sort the idle mixture issues from the other thread?

I plug the O2, and disable PTT, now the VF is from 2.0 to 3.0, the wide band at idle display 18.X but like other members said, may be will be for a exhaust leak.

Now my problem is the stalling only in fist gear, because I can go to the track to test my car :cry:

Why on earth would you take a crippled car anywhere near a track let alone push it hard until you sort the problems it's having?

Sorry I just don't get this at all, may as well empty the coolant and oil and save time on destroying the engine.

Its a tuning problem. Im assuming you have a wideband and a laptop to play with Tunerpro correct?

Far too many variables and compromises involved doing it that way and with how cheap standalones are now it makes no sense to take the risk.
