It's got 50K on it, but it's new to me! A good compromise to an old tacoma so I can fit a baby seat for the little one on the way. About to replace the plugs with some E3's.

Engine light came on, gascap. Replaced it with Mopar non-locking cap(heard locking was an issue and don't fit right) and the light is back on.

Any suggestions?

 

Welcome to the site. You could ask the guys in the section that pertains to your vehicle such as the third generation Ram or second generation Durango section. You can reset the system by disconnecting the negative battery terminal for a few minutes and see if the light comes back on. I would stay away from the E3 and stick with stock Champion copper or Champion Iridium,

Thanks, posted it there as well. Already tried disconnecting the negative battery terminal, light keeps coming back on.
