2002 Intrepid 3.5 with oil light flicker

Hello, I just picked up (friday) my Intrepid. What a beautiful car! It has an engine light on however, (forget the code exactly) but its something to do with o2 sensor left side behind cat?

Anyhow, my real problem is that the car seems to start and shut off quick unless I "nurse" it with the gas pedal. After 10 seconds or so, (not long at all) it stabilizes and all is well. Also after driving for a bit (half hour plus) the oil light will flicker at each stop. The idle gets down very low to a point where I believe its going to stall. It never does but...

So the question is... Is the o2 sensor the culprit, and if not, what do you think I should look at.


Thanks for your time, I love the car, should have gotten one of these many moons ago!

First off welcome to the site! I have an 02 as well, I love it. Your oil light flicker could be simple or serious. First off, do you have a 2.7 or 3.5?

Almost certain that the oil light flicker is a side-effect of the low idle. Oil pressure is very much dependent on engine speed, especially near idle. Low idle will definitely cause flicker. So don't troubleshoot the oil light flicker as a separate problem. Fix the other problem and the oil light will take care of itself.

Good day folks, today I checked the code P0138. It was the only code. Today, it idled for 45 minutes (waiting for the bank to open), oil light never came on, car idled perfectly the entire time. It definately passed this test. Tonight on the way home the idled dropped low (below 500) for a few moments, but picked right back up, no flickering no nothing.

What's the thoughts on the code?

P0138 is an 02 sensor code, voltage too high. But with your flicker, try a different oil pressure switch. 24 bucks from the dealer. I would only get OEM when it comes to anything sensor related.

True - OEM only on that. But with the flicker coinciding with fluctuating idle, I have to think to fix the idle first and then replace the switch only if needed since the idle needs to be addressed anyway. Very likely good idle will fix the oil light flicker.

Would the o2 sensor help my idle, or am I looking in the wrong place
