My 92 Loyale started having some problems starting in the past couple days. When the engine is cold, it cranks right over and starts. When the engine is warm, though, it cranks for about 10 seconds and then slowly sputters to life. Once started it runs fine. I've never had this problem, only have had it the other way around. Any ideas?

It's most likely the temp sensor that the computer uses. Next time you have the problem open your door and try te smell the exhaust. If it smells really rich then the sensor is the problem. What happens it the computer thinks the car is cold so it adds more gas. This sensor is on the passanger's side of the intake manifold towards the back of the engine.

I agree with Keith on all counts except...
This is an SPFI and if I am not mistaken the FI coolant thermosensor is located on the goose neck.
(I think Keith is refering to a MPFI/Turbo model.)
Another thought is a sticking IAC valve.
If it sticks open - could it lean the mixture to the point of no fire?
As it is just a throttle plate by pass, this theory probably holds as much H20 as a toilet paper roll

You're right skip. I don't know why I was thinking it was an MPFI.
