I'm a 62 year old lady with a 98 Caravan SE. 134K mi and just had tranny rebuilt new sway bar links and motor mount. Engine runs great, no leaks of any kind. The Check Engine light just came on this morning-I'm 1K away from needing oil change in miles, but it's been 3 mo.
Should I just go ahead and have the codes checked? Getting an oil change anyway.

Where are the tech sections?

 

Welcome to the forum. Yes, get the codes read. That's the only way you will know what's wrong. I have moved your thread to the Caravan tech section.. From the main forum page, just scroll down to find the various technical sections.
