Cold starts take a few starts

When my car cool off good, for example say the next following morning i try to start the car, it starts but then idle drops and it dies right away, i can try it again and it will do the same, unless i use the gas to keep the idle up for a few seconds, then its good.

One thing i can thing is, maybe i need to clean injectors, or fuel pump is going out?

any ideas?

You might need to adjust the idle via the tps...

well it idles at about 600-700 rpms but its the cold start that just drops to zero on a cold start.. whats tps?

I had that prob when I first got my 40.
I changed the fuel filter and it never happened again.

just incase you have a question lol
theres also a chance your fuel pump may be going
