Please help! I have a trip to Atlanta tomorrow evening, and I'm wondering if it's even safe to go. I cleaned out my engine with a bit of water and simple green. I dried it out for about 3 hours and then drove for a bit. After about 10 minutes - the check engine light appeared, and the 4runner started feeling different. A little shaky around idle, and I guess that's it. Is it safe for me to go to Atlanta? I know that's a question I really have to ask myself, but I just thought I'd see if anyone had a similar experience. Thanks!

And I feel like a complete idiot. So thanks for your help!
