2 most common reasons CEL doesnt work: 1) it was on for so long the bulb burned out. 2) CEL was on and PO removed the bulb so any prospective buyer would think it wasnt on, increasing the value of the car. Happens more than you would think.... lots of dishonest people out there.
Ha! The bulb should be burned out because I remember pulling codes off of it a few years ago. I will get the build replaced soon then. The women in my family tend not to worry about their cars. So I am hoping the low oil pressure light just needs the sender replaced... Here to crossing fingers...
Just thought I would point you to the thread that I started and am pretty much done with. It talks to the Oil Pressure light (flickering anyways). I just did this change out on the Oil Pressure Switch (recommend renting/buying oil pressure gauge and putting on before swapping sensor) and the Cam Synchro and Sensor.
Hit me up if you need any help with those things. It's fresh in my mind.
Okacookie, for a good how-to tutorial for r&ring the oil pressure sender switch on a tec, click on Forums at the top of this page, then scroll down and click on Maintenance and Repair and go to page#773. Scroll down to: Finally Found My Oil Leak by maceslin (3-14-05).
There is no knocking or chatter that I have noticed... My wife is the one driving it and says there is just a squeal once in a while. I am driving her old ford probe that snapped the timing belt, and that was a blast to fix.
