I’ve done some searching but didn’t find anything. My truck is a 2004 Titan LE crew-cab 4x4 and totally stock with 197,000 miles and I am the original owner. The only modification I have done was opening up the air intake in the filter box. Spark plugs and serpentine belt replaced with OEM parts around 110,000 miles. All services and recalls performed through my local dealership. Most of my driving is long distance on the interstate and I love this truck.
My problem – over the past several months my truck has developed an engine vibration during cold start ups. The steering wheel and mirrors shake, but not violently. Just enough to see and feel, and it has never done this before. It happens regardless of the outside temperature and the transmission being in P, D or N, or while sitting still or moving. After the engine warms up to operating temperature it goes away. The vibration is there sometimes when starting the engine while warm but not completely cold.
On cold start up the RPM gauge is at about 1100-1200. If I touch the gas pedal to bring the RPM’s up a tad the vibration goes away. When the engine is warm the RPM’s drop to around 500-550 as normal and the vibration is gone, whether in gear or not.
The Check Engine light has been on for years, and $80 at the dealership told me the gas cap was loose. The passenger side exhaust manifold sounds like it is cracked but it’s not loud. There has been no change in performance or fuel mileage.
Any feedback would be greatly appreciated!
