I just "inherited" a 1996 318ti California from my college-age niece. It was towed to my house with the #2 plug blown out. It was also very low on coolant, oil, and power steering fluid. The threads in the head did not look damaged (surprisingly) so I tried putting a new plug in and was able to torque it without any problem. I went ahead and replaced all 4 plugs. I also checked the CR codes (0300, 0302, and 0304).
The engine will start and run fine. However, after running on the freeway for 15-20 minutes, if I pull off and then accelerate sharply (run the rpm up to ~5000 rpm) the check engine light will flash 4 times and then stay on. The motor then runs very roughly (basically runs on 3 cylinders) for the duration. The next day, it will run fine again, CE code show 0302. I did check that the plug is still tight in the head, and that both ends of the wire are secure & tight. The wires themselves are very oil soaked as there are bad oil leaks (the oil filter mount is a obvious large one).
One other odd thing that may or may not be relevant. Before its starting to misfire, while driving on the highway, it beeps twice. Just a quick "beep,beep", no warning lights or other issues. Any idea what that might be?
I don't want to spend much money on this thing until I have a better idea of what may be involved. It needs a lot of other stuff like shocks/struts, interior work, tires, etc. Looking for suggestions of what to look at/try next. Plug wires? Have the coil pack tested (no idea how to test myself since it obviously sparks when I start the car)?
Thanks.
