Well, heres the problem.My car has had a little problem with stalling and it seems to be since i put in the 24# injectors.It just seems like a logical explanation. it started to be just when i put the car in reverse that the RPM's would drop and it would stall once in a while. THen it started to stall a little more. Now it has gotten alot worse.It got to where i would be making a turn and the rpms would drop as i let off the gas to turn and the car would go to stall, now if i go to a traffic light and give it gas from a dead stop it will not do anything when i push the pedal and then it stalls.Now this happened 5 times today and its getting to be a dnagerous situation. I am now power breaking at the lights and it helps so the rpms dont drop but its not gonna be good for my brake shoes lol.Any ideas on what i can do? I am gonna wait for some of you guys to chime in before i attempt to do anything. THanks in advance

First make sure you Mass Air is calibrated for #24 injectors. You say it happened after the install, check your fuel pressure, is your fuel pump upgraded as well...it's a long list of possibilities, but I would check you mass air meter and fuel pressure first. good luck

You replaced your IAC right? Did you get a Wells or did you go to ford? The Wells one from autozone has to be flipped backwards compared w/ a stock one or it doesn't work properly.
Have you pulled codes? I would assume--and this may be incorrect--if your O2's are working correctly and your MAF is calibrated correctly, and your injectors are in good shape, you shouldn't be running rich because the computer should increase/decrease pulse widths to maintain the proper fuel.
Have you checked your TPS?
HISSIN told me when I had this problem that the VSS controls idle when you hit the clutch, so maybe your VSS is bad?

actually, the VSS will maintain a higher idle (~1500 rpm) when you are at a rolling idle (idling but the vehicle is moving). this is to keep the car from stalling when one goes from running at speed to being in neutral but rolling, where one still will create a load with the PS, etc. it also keeps the idle from simply falling so fast it cant be caught in time. T.U., it is actually not dependant upon the clutch or its position, but rather the act of speed (the VSS is in the trans).TheUser said:
the IAC and puter work in conjunction to accomodate load. when you mention that you have issues with stalling while turning, this further makes me worry about the IAC. as one turns, engine speed can be low, while load is high (power steering, brake and turn signal lights, etc). the IAC should compensate for this if working correctly.
ditto for cold start issues, if you have those. pulling codes would really help if you can. and with the car in this condition, i would recommend not driving it, as it is unsafe (as you astutely commented upon).
good luck.
