hard to start below 50F
It only starts when I press the accelerator when the weather is below 50F or so... Above that temp, no problem whatsoever. If I don't throttle slightly for a few seconds, it stops but once I throttle slightly for 15-20 seconds, it picks up and if I drive it immediately, it idles perfectly OK within 100 yards. Odd as it gets (to me anyway)... ALL sensors/switches have been changed within the last two years and I am suspecting a failing IAC. Any ideas from those of you who had the same problem? Thanks in advance...

Im having the same problem except I have an '88 L98. I'm thinking its the MAF but yours is speed density, so not sure on your end. Map sensor maybe?

Re: hard to start below 50F
Pull the spark plugs. They're probably carbon fouled from all the cold starts.
Might be time to replace. A good throttle body cleaning, idle control motor and check all the plug wires and air filter.
