rough idle
Has anyone else had this issue... my truck has a rough idle when it gets up to normal operating temperature. only problem is that it does this every now and then. i think i have it narrowed to three things, EGR, fuel filter, or coil/plugs. any advice??
|
What truck?
How many miles? What mods? Service history (breif)? |
04 FX4 3valve 5.4l. no mods 152000 km. as for service history, unknown as i had bought it used from a dealer. i just did the oild and before i took the truck home i had the dealership change all the other fluids.

Start with cleaning the IAC-it's easy, and the maf then go from there. Are there any codes?
|
have you gotten any codes ? sounds like a plug ti me mine dones the same it the #7 plug that gets wet
|
No IAC on that one. Fuel filter and clean the throttle body. What's 152 kms?
About 94,500 miles so a plug change is due IMO. |
Like others have said.. cleaning the throttle body and MAF should help a lot..
