Not sure if this fix is the same as the gas pedal post but here goes.  Sometimes when starting the car it will die without the gas pedal being held in just a bit.  If you take your foot off the pedal when it's acting up it will die.  However after about 5 to 10 seconds of holding the pedal down just a bit it runs fine and idols great.  Sometimes it's in the morning after sitting all night and sometimes it's after driving and sitting for 5 minutes.  Sometimes it goes days without acting up.  I did discontent the battery for an hour and it ran great for 4 or 5 days after that.  Any thoughts?  I did pull one of the front plugs but they look ok.  The car only has 100,000 miles but I've only owned it for 15,000 miles so I can't tell you if any work has been done except for the notorious gasket.

I assume you have a 3.1 liter engine?

If you look in between the throttle body and the intake plenum near where the throttle cable is attached you should see the fuel pressure regulator. It will have a small vacuum hose coming out of the top of it and a fuel line coming out of the bottom. Remove the vacuum line and start the engine. If fuel comes out of the the regulator where the vacuum line would have been attached you found the problem..... Or at least "a" problem. Replace it and you should be good to go.

Did Jeremy's solution fix this problem? I was wonder if it could possibly be a dirty MAF sensor. Are you throwing any codes?

    • Way to get him out MM!  I'm sure he appreciates it.
    • I believe some units come with maps of some lakes but probably wont have any real detail as far as contour lines.  I think most will have a map of the US but when you zoom in you wont get much for detail on lakes and If they do contours will probably be 5-7ft apart.  If you want to put data on a card you will need a zero line card for mapping. About $150 i think.  8 hours should give you quite a bit of mapping.  Best would be to buy from a retailer so someone with knowledge of the product can show you how to run it.  You might be able to take some snap shots of sonar and put on a blank card but don't think you can map with it. I would get a Lakemaster card for the area(s) you want to fish.  Worth every penny.
    • Turkey season is over for my nephew!! It was a long season with many hours spent in the blind. He seen more turkeys then ever before and had a toms close enough to grab. It is going to be nice to sleep in. Until fall turkeys!
    • Heading up to Devils in a couple weeks and again later on.  Doesn't look like a lot of activity on here.  Tryng to get an idea whats happening before I go.
    • I have been out the last two days locally and haven't set the world on fire. Caught a few each day, but fish have been scattered. Lake is loaded with curly leaf mats this year, so that hasn't helped things. Once that starts dying and weather warms up, things should pick up.
    • Nada for me today. Had some hens come in to give my decoy some company today, but no toms. Sorry I wasn't able to help out on the scoresheet this year. As always, learned some stuff that will make me better next year.
    • We caught plenty of bass this weekend.  However most were small 12-13".  Deep fish were less than eager to bite.  Still seen a couple guarding nests yet. Small plastics fished slowly was by far the best tactic. Only found a couple decent fish, biggest being 19.25".
    • We called at about 4 had them as close behind the blind but never came around for the nephew 
    • What great fun on a 4-weight fly rod!!  Those are dandy panfish.
