Hi guys,
I experienced a pretty weird scenario with my P5 this evening. It's a 2003 P5 auto with 125k miles. I'm not new to troubleshooting cars, but this really has me in the dark. The car has no modifications other than a pair of Hella horns (which are wired up properly with a fuse and relay.)
Here's what happened:
- I accelerated onto an onramp to 70mph, and merged over two lanes.
- The car "jerked" and the torque converter unlocked (I think?), making the engine sound like it downshifted to about 3500 rpms.
- I looked down at the dash and all of the lights were on, the car had no ignition.
- The transmission was still in gear and the motor was spinning, but had zero throttle response and was deaccelerating.
I pulled off to the side of the road and checked transmission fluid and oil, which were normal. Temperature was normal. Everything looked fine. I was on my way to school for a final exam, so I started it back up and drove it to school and back home.
I've looked over the car a little more and everything looks great. There's no check-engine light and I scanned it for codes - got nothing back. What gives? The only thing I can think of would be a bad ignition switch. Unfortunately I haven't had any issues with it starting or cranking previously. I want to see if anyone has any ideas before I load the parts cannon and start guessing. Thanks!
