I have a 91 325i engine swapped in my tii, the car has ran perfect for years. but recently. I have noticed that on cold starts it wants to die out, I let the car warm up for a few minutes and it idles back to normal. I also notice if I am at a stop light and slightly quickly hit the gas peddle the car feels like it wants to stall, almost as if there is not enough fuel. I have to gradually press the gas peddle not to get that effect.
I replaced the OEM injectors with some mustang 4 nozle ones, since my oem ones were clogged with junk. but note that I had this issue with the OEM ones on the car. so I dont think the upgraded injectors are causing this issue. I have also swapped the ecu just to make sure it was not the DME, but the problem consist. I am thinking maybe a vac leak? ICV was swapped also with no difference. Blue and white sensors for the temp gauge were also replaced.
