I let my car sit for 2 days and turn it on and it runs decent does not sputter much but after 5 min after being warmed up it sputters , so then I run it like that for a bit and go pump gas after pumping gas it takes another 10 min for the car to run right again , any ideas on what it could be ? It gets really annoying as I don’t drive the car everyday. It’s a sbe 306 with 24 lb , spray pattern injectors and a 255 lph fuel pump . Since it’s cammed it runs even worse with the sputtering.

Have you checked for codes? I will guess not, you can have codes present without the cel on. Go to the 5.0 technical/how to threads and click surging idle checklist, go through the list step by step and it will save you time and money in the long run.

You guys with idle/stall problems could save a lot of time chasing your tails if you would go through the [URL=" http://forums.stangnet.com/showthread.php?t=698148"]Surging Idle Checklist[/URL]. Over 50 different people contributed information to it. The first two posts have all the fixes, and steps through the how to find and fix your idle problems without spending a lot of time and money. It includes how to dump the computer codes quickly and simply as one of the first steps. I continue to update it as more people post fixes or ask questions. You can post questions to that sticky and have your name and idle problem recognized. The guys with original problems and fixes get their posts added to the main fix.



It's free, I don't get anything for the use of it except knowing I helped a fellow Mustang enthusiast with his car. At last check, it had more than 250,000 hits, which indicates it does help fix idle problems quickly and inexpensively.
