Car stalling (AUTO)

[DennisC]

I've had problems with what seems to be a faulty water pump. but i have another problem and that its stalling

my car is an auto 1995 240sx after a few minutes of warming up and i put it on reverse the car stallsand it takes alot of cranks to get it up and started again, and once it doesthe car hessitates but it dries fine afterwards

the shop where my car is said it coud be the TPS sensor ?

my car did that and it was a loose coolant temperature sensor.

is that part of the water pump ?

I can't find that part on the service manual ?

No, There are 2 temp sensors, one in the lower radiator hose & one on the intake manifold (near the fuel rail toward the front of the engine, right next to the coolant bleeder screw).

I believe the one he is talking about is the one on the intake manifold. start the car, wiggle the harness connected to it and see if it makes the car sputter/surge, etc.

does it only stall on reverse? does it ever stall @ idle when you are driving? is there any surging/weird idle? What is your idle rpm anyway?

yea the one im referring to is like in front of the intake manifold or say between intake manifold and radiator. its red. it will stand out. but mine was completely unplugged but ive heard problems of the connectors getting gummed out and easily cleaned with electric parts cleaner.

we cleaned out the TB it was a real mess in there we checked all the cables and plugs to the tb and intake manifold and problems solved!

guess the lesson here is always clean your TB lol..

My car is doing the same I also have a 1995 240sx base auto. (I have changed plugs new fuel filter and sea foamed the crankcase and vacuum lines) I can rev it as high as I want and throw it in reverse and it will still die. Also the r.p.m tach is all over the place when I do get it started and in drive.. Stalls every time after about five minutes of driving (forewords) Could I also have a throttle/intake issue? I really need to get this fixed..
*Takes multiple times to get it started
*stalls as soon as it is in reverse
*tach is all over the place in drive and ends up stalling after five minutes or less of driving.
Anyone? help?
