Hi all. I have a 91 900S and this morning the check engine light started doing some interesting stuff. At idle the light flashes 4 times and then pauses for a second and then flashes 4 more times. This pattern will continue until I press the accelerator. Once the RPMs go over about 1200 the check engine light stays solidly illuminated. At first I thought the light was just flickering at idle. But it definitely has a very solid and repeatable pattern. Is this some sort of a code indicating what is wrong? Oh, the car seems to run fine at all engine speeds but I have noticed that over the past few weeks my fuel economy has been up and down a bit. The check engine light just came on for the first time today (O2 sensor and air mass were replaced just 6 months ago). Thanks! mark
