Car stalling cold morning?

[br0ck]

Car having morning fever? HAHA

Here in toronto... some morning i let the car warm up and start reversing out of the drive way and shift into drive the car just stalls up and dies. Have tried almost everything to figure out why it keeps locking up. Just recently had alt changed, batt, water pump.... And still seems to keep giving me a sitting duck form. Any ideas on why ?

car dies when warmed up or when still cold?

My mx3 does almost the same thing as yours...but with mine if i fire it up when its cold it goes out fine when i reverse but when i throw it in drive ..not all the time but sometimes and i push the gas in a bit it fights and then it stalls..and when it stalls it is a huge b---- to start back up agian ..but if i let it warm up from bein cold then go its fine..and ive had it checked for fuel problems and everything and they have found nothing so is there anyway to stop this from happening becasue cold or not it shouldnt do that..i have a dohc auto tranny rs model mx3 any suggestions for me and him would be great

my 95 dohc does the exact same thing too, anybody know whats wrong?

sounds like radiator sensor/coolant sensor. When engine is cold it keeps rpms up until engine warms up.

yep i would try the coolant temp sensor. not only will the ECU fail to increase the idle speed but it will also inject too much or too little fuel because of the incorrect temp reading. when you replace the sensor, be sure that it is the sensor for the ECU and not for the guage. ECU sensor has 2 wires, temp guage has 1 wire.

so there is a 2 wire and a single wire sensor?
same with a BPT setup?

if there is a 2 wire sensor, where is it?

thanks
