I changed a badly cracked muffler two days ago. Later that night driving my check gauges light came on for a few seconds, off for a few minutes, then on again. It did it again this morning. Because of the timing I'm wondering if the new muffler could be the problem. It was a few inches longer than the old one. It also started randomly slowing down for 2-4 seconds when I'm going 45-60... that started a few days before changing the muffler. not sure if they are related.

Chances are this is a coincidence; the high-pressure light comes on because the oil pressure sender is probably bad. Below is the location so you can change it out to fix the problem. Check out the diagrams (below). Please let us know if you need anything else to get the problem fixed.
