Having problems with your 2003 Ford F150 Regular Cab ?
[email protected] my 03 f-150 is very sluggish on take offs at stops and exceleration! i installed new fuel and air filters still same problem
Check fuel pressure, also common problem
I had a L-shaped rubber hose at the top of the engine near the firewall collapse and snap in two. I replace the $7 hose and have had no problems since. I checked all of my other vacuum lines and replaced one that seemed dry-rotted. Good Luck!
