I am having an intermittent misfire issue with my 996. It started a few months ago, when the battery ran down after not driving it for a few weeks, and I had to jump the car to get it going. After a few miles, I got a CEL and the car started to misfire. Upon arriving at my location, which was just a short distance away, I turned off the engine and went about my business. Upon returning to the car, it ran fine. No CEL and did 65mph all the way home, which was about 20 miles away. All was good, until a couple of weeks ago, when on a slow drive, I got a misfire and the CEL came back on.
Hi all The engine light comes on my 996 every so often, then goes off a few weeks later. I wasn't to concerned as the car drives well. So I got round to plugging it into the Durametric to look at the fault codes.... I've got loads of codes, P1340, P1531, P0300, P0306, P0304, P0305, P1585, P1319, P1318, P 1316, P1317, P0301, P0303!

The issue I have is a "tapping" noise on the engine on idle and a slightly eratic idle - its not
My 2000 Boxster S w/105k (body) 40k (engine) is acting up. Last fall, I got caught in downpour and inches of standing water, getting splashed hard by other cars. The CEL started flashing and the car was nearly impossible to drive past 3rd gear (no power and bucking) until I could get off freeway to let it dry out. It had several misfire codes set. Ever since then, it's been a little less smooth than I had been accustomed to, and now it is misfiring and bucking below about 2600 RPM all gears, all temps, but ONLY with high throttle opening (e-gas). Tipping the throttle in seems to be fine. H
