I keep getting a engine coil misfire on #5. I had the coils and the plugs change but it wont go away. it's running very sluggish. when i warm my car up when its cold outside it sounds like my engine is whistling......SOMEBODY HELP
My 2000 Jag S-Type started cutting out really bad. I took it to the repair shop and had it put on the engine analyzer which stated I had a misfire on #2 cylinder. Coil and plugs were replaced. It is still doing the same thing.
I HAD TO REPLACE MY IGNITION COIL. IT IS WAS ACTUALLY SIMPLE TO DO BUT THE DEALERSHIP WAS GOING TO CHARGE A ARM AND LEG TO REPAIR. I ORDERED A NEW IGNITION COIL AND REPLACED IT MYSELF. IT IS AS SIMPLE AS REPLACING A SPARK PLUG.
Engine fault light on. Misfiring sound when cold. Can't accelerate quickly without the engine shuddering. If acceleration is steady it'll go at full speed without an issue. Concerned this will be dangerous in emergency situation. A mechanic diagnosed coil issue and I had ALL the coils replaced. The problem returned within a few months, now different mechanic (at Jag dealership because field tone didn't want to touch it again) has diagnosed same issue - coil fault on cylinder 5. I don't want to repeat exercise in a few months again. They can't tell me WHY it the coil would be faulty.
I purchased a 2002 S Type in 2004 with numerous problems but 12/2007, the replacements and repair: 1. Excessive vaccum leakage; replaced upper & lower intake gasket (12 parts); upper & lower elbow hose & spark plugs (6);elbow breather & tube
2. Valve covers leakage; replaced all coils (6)
I had the same problem ignition coils 1 and 5. But my car runs great what sum mechanics dont kno is the diagram and numbers of where the coils are located. Also when replaceing the coils replace the spark plugs as well with platinum or double platinum. They last longer!!!:-)
Ignition coils are readily available online, and they replace similar to the sparkplug procedure. However access is limited by the intake manifold. Take your time and replace the gaskets and spark plugs while you're at it.
