Hard to start when warm

Hi Brad, it will start if I push the pedal to the floor,its hard to start if I drive it for 10 minutes or two hours , as soon as it warms up a little that's the only way I can get it to start. And this problem started a little at a time .

Do you have a multimeter so that you can test the temp sensors.
There are a few step by step on how to check them, maybe even in our tech or tips section. Are you comfortable with using a meter?

Yes I have a little experience using one, just don't no the step to checking them and where it's located

Paul, I looked in our technical libary and I found this in under 5 min

at the end of the instruction Kurt say this

You can check the connection to the sensor by disconnecting both main plugs
to the brain in the passenger side footwell and measure the resistance
between PIN 13 to ground (PIN 17) of the LH connector. You should get
around 2 kOhms for engine cold and 200 Ohms for engine warm. While
measuring, get someone to wiggle the cables around the connectors a bit and
check that the resistance doesn't change (otherwise you have contact
problems)

The pin numbering starts with 1 where the cable enters the connector and
the row with the 18 pins (vs 17 on the other side) is the one Pin 1 - 18
so it's:

1 2 3 ... 18
cable ->
19 20 21 ... 35

My money is on idle control valve.

Although that is more of a too-lean, rather than too-rich theory.

Thanks for the extra help guys !!!! As soon as I rest up from my angioplasty I had 3 days ago ...I will begin my search
