Hard Starting 99 EXP
Hello,
My wife has a 99 Explorer with a V6 4WD package. Lately her explorer wont start easily. She has to hold her key for a few seconds while the the truck tries to start. We live in the greater Seattle area and it has been very wet here lately. I was thinking also that it might be a bad tank of gas. I have put a can of Dry gas in the fuel tank but it hasn't seemed to help.
Could it be dirty injectors or a bad fuel pump?
Any help would be much appreciated.

The idle control motor is very easy... under the plastic cover it is held on with two bolts.
Intake gaskets are a little more involved, but still not that difficult.. it's all simple nuts, bolts, and hoses. The "gaskets" are more like seals that look like rubber bands.. they get hard and brittle and allow a vacuum leak when the vehicle is cold, making it hard to start and idle rough the first few seconds...
As the engine warms up the seals warm up and seal up.. then it runs fine until it cools back down.
If/when you do the repair you'll notice the new seals are redesigned, and are about twice as thick as the originals.

Do them both... on this if I recall correctly no antifreeze travels through the intake. Hardest part is the injectors.. use new injector seals and be careful to use a little lube so they don't roll on you on installation. It's no fun having fuel spray everywhere!
Once you have the upper off, only a few bolts and the injectors are in the way to do the lower.
Good luck.
