02 trouble starting

[tucker1]

My 02 is having trouble starting like once a day. It seems as if it always happens after the car has been run and sits for about an hour. It either cranks for like 4 seconds before starting, or it starts, idles real low for about 1 sec and then runs normal. Could this be a bad starter or what?

Probably a bad IAC valve.

What engine is in it? If it idles low and then comes back up, maybe the IAC...

SOHC or OHV? Do a search for IAC. You will come up with tons of info. It's called the Idle Air Control...I think...i'm somewhat of a newbie here myself. I do know that that sounds like symptoms of a bad IAC. Odd that it is bad on such a new truck...how many miles are on that thing? I got 74K miles and no IAC problems.

Its an '02 model. It has the SOHC. OHV doesn't come in the 2002 model.
