Audi A4 ProblemsEngine Oil LeaksEngine Misfire Due to Failed Ignition Coil, Spark Plug, or Ignition Wire
An ignition coil or spark plug may fail unexpectedly resulting in an engine misfire and possible illumination of the Check Engine Light. Vehicles equipped with spark plug wires may also develop a misfire caused by a failed spark plug wire.
Clogged drains can allow rainwater to accumulate in the plenum tray (at the base of the windshield). The water may leak into the vehicle's interior, brake booster, or electrical components, which can lead to major problems. Our technicians recommend keeping the tray clear of leaves, pine needles, and other debris.

My 98 has a big turbo kit and sometimes it spudders or hick ups when accelerating/shifting. It also pops/back fires when shifting under load. Why would it start this now? Never had these issues when first bought the car?
