Hey ya'll. I bought a 2000 Intrepid with 2.7 ltr and base model. Has 84500 miles. Here's my problem. It had oil changed 2000 miles ago. But, that was November 2010. So 2 years ago and 2000 miles ago was when last oil change occured. Now, I'm pretty sure it got drove those 2000 miles after the oil change in Nov 2010. Then sat for about a year. I drove it and its excellent right now. I'm pretty sure ya'll are gonna tell me to change oil right away. But is there anything else I should do mandatory? And anything else that you would do that's not mandatory but prob needs to be done as well? It sat a year I'm sure. Had 82500 when oil was changed. Has 84500 now. And lastly, is there any upgrades I can do. There's a you pull it yard right up road 5 miles away. Like maybe a trip computer, cmtc, or leather seats out of another car other than Intrepid, or anything you can think of. Can't give me too much info or advice. Thanks a whole lot ya'll. Really mean it. Thanks! Oh yea, I forgot to mention it showed codes p0455 and p01494 on my obd2. Not sure what to do bout that either. Thanks again.
