car is dying

[Boobie900]

car trouble help!!!!

This started on monday. When I am driving, I will come to a stop light or slow down for a turn. The car will sputter, like it is starving for gas, then sometimes it will die. I can usually start it back up, but once I put it into drive or reverse, it likes to die again. I can sometimes start it, press the gas, the put into drive and it will go. Sometimes after driving it for a few miles, thenit is fine. I changed the gas, thinking it was bad, but that wasnt it. The only thing i have touched on the vehicle lately is I checked the air filter. Also when I turn the key over, the battery light is on, but when im driving, it isnt on. Does anyone have any suggestions? Fuel filter or fuel pump? thanx

taking your negative cable off of the battery for a few mins may help if you changed the air filter. Your engine has a memory for its fuel requirements and if you change the filter the air/fuel ratio changes. Taking off the battery cable will clear the memory. Try that first

Could be a stuck IAC valve that controls the idle speed. For example, if you unplug the IAC electrical connector on a running engine it will likely stall. If you ride your foot on the gas, it will operate normally. Putting transmission in gear makes it even more prone to stalling.

Same symptom will happen with a sticking fuel pressure regulator, except that applying light pressure to the gas will not help. The same with intermitant fuel pump or defective fuel relay.

Your battery light among others will come on while starting and then go off when driving, that seems normal.

let me ask this: When it stalls at stops, would you say it acts like stopping with a manual transmision without pushing in the clutch? I've seen theexact same behavior from a car that had a sticking torque converter lockup clutch (TCC). TCC doesn't normally engage until the vehicle is above 40 mph, can you drive around all day -- never get above 35 -- and have it behave normally? TCC (and 3-4 shift for that matter) are controlled electronically. If you unplug the TCC/3-4 connector at the transmission, does the problem clear up? You'll lose TCC lockup and 4th gear, but it's good enough for diagnostic purposes.
