Just rebuilt my 2004 F150 5.4L 3V engine
and put it back in and getting a rough idle. Scan after I cleared the codes are P0119, P1289, P1290, P0171 & P2198 are coming up.
JA: Is the rough idle intermittent or consistent?
Customer: Intermittent. Also the temp guage is normal for ~1 min then pegs on the cold side
JA: What is the model of your '04 Ford?
Customer: 2004 5.4L 3V Lariat
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: Fix it myself. I shot some throttle body cleaner in the throttle body and it seemed to help the rough idle but just came back.
JA: Anything else you think the mechanic should know?
Customer: I had to take the Intake Manifold back off because the rt side harness was stuck and the intake filter broke on the front side. I duct taped the area it broke thinking it should be fine. The engine light was on before and is still on.
