I saw the CEL come last night and noticed my oil pressure gauge was about at 1.5-1.8 bar. I read in my manual for my 92 UrS4 that low oil pressure would cause the CEL to come on. So I went to change the oil today and the oil filter is on way too tight, couldn't get it off with a standard filter wrench. I had to get to work so I tightened the plug down, filled her up and went to work and watched the pressure gauge like a hawk. I noticed that she's not running pegged at 5bar while on the freeway (which she usually does) and when at a light she's still running about 1.5-1.8 bar oil pressure and the CEL keeps coming off and on. I checked the oil when I pulled into the parking lot at work today and it's full.
Yes,at this point I need to have the code pulled on it, but would a crazy tight oil filter cause this?
