need major help

[1fast92]

ok i need some major help. i have a 92 talon n/t 5 sp. has 144k on motor, new head and here are all the new parts. new o2 sensor, new mass airflow, new IAC, new plugs new wires, fuel pump, fuel regulator, clutch, coil pack.

now the problem. Have a horrible cold start problem. if its around 0 degrees takes at least a 1/2 hr to start. then when it finally starts have to wait till at least 10 min before hitting the gas or it will stall. had a horrible idle problem, but replaced the IAC motor and the BSS screw and it helped just not cured. i idle about 800 to 1000. it has a horrible "stumble" both on idle and during the range of accleration. espically about 90 mph. it almost like it cuts out and its pretty violent.

compression is fine, all cylinders are firing. if it sits more than 2 hours and totally cools down, on a warm day takes probably 8 or 9 revolutions of the motor to start, and then it like only idles about 500 and just horrible idle.

coolant sensor is also fine. checked the tps sensor and its ok, its within spec. also checked the injectors and all 4 of them are at 13.9 to 14 omhs.

im at a loss what to do does anyone have any ideas? please help

Have you checked your fuel system(pump,filter,regulator). You probably have a fuel delivery problem!!!Check those parts out and post your results!

ok another question. i have the 6 bolt motor, and i believe its running the 1g throttle body, it has the 3 vacuum lines on the top of the TB, which is the better TB? the 1g or the 2g? and if the 2g is better is it possible to swap the 2g onto the 6bolt engine?
