I bought my 97 M model at 36K miles, and have driven it for 4 years. Now has 88K. On a recent highway trip it started missing when ever I accelerated, but would smooth out when I let back off the gas. This has been a gradual onset, but seems to be getting worse. If I start off very easy with just a slight amount of throttle, it's okay, but any excess throttle and it drops down to three cylinders. Is this a spark plug thing? Any ideas? Thanks.
