Question
My 2001 Chevy Tahoe idles low when I let off the gas and sometimes dies after I let off the gas and slow at a stoplight or to turn in.  The RPMs drop to 400 or so and it dies about a third of the time.  I just replaced the fuel filter to see if that was the problem, well, it wasn't.  Now I am thinking that it is the fuel pump, but that is $265 and a day out of my weekend to replace.  Got any ideas or a test that I could run?

Answer
Hello Filus,
Sorry for the time, but I haven't been able to log on for a couple days.
Yes, there is a fuel pressure tester, and a test port.
Some parts houses will loan it, or test it for you.
Your problem could also be the idle air control valve.
