So I was coming home from college for xmas break and I was doing about 70 and the car sputters, fires up again, and then sputters and dies right away. I thought it was moisture in the gas but I put gas in it and some heet and I am still having issues.
The car will fire right away and idle for about 20 seconds before it sputters and dies. However, if I keep it above 3000 rpm or so it will stay running as long as I want it to, but as soon as I let the revs drop down below 3000 rpm or so it sputters and dies right away.
I am pretty sure it isn't moisture in the gas or a fuel pump because above 3000 rpms it runs great. I have heard fuel pressure regulator or throttle position sensor could be the culprit but I really have no clue.
Any help would be greatly appreciated!
