INFO 97 seville 91 k ,....4.6..........within the last 5 weeks or so, about 5 weeks apart, i've gotten the low oil pressure warning. Usually when the car is in use for about 30 mins. It does not overheat other than the Digital reading. Many posts here in the past have noted this warning, with no other symptons.

Today, when i smogged the car, i was told my catalytic conv. is defecient.
Probably needs a new one.

The car does run sluggish, sometimes, probably only noticeable to me since i now the car so well. My question is ,.... Which of the 2 is the more likely suspect?


And what am i looking at for each job.?

thanks,

gee

A clogged CAT will cause the car to be "sluggish".

Oil pressure might just be a bad pressure switch. We rarely hear of oil pressure problems. Try pulling the plug first and cleaning it with Brakleen. If it is oily, that could be the problem.
