um, eric.....i've been in a situation where the car's motor was turned over with the dme disconnected and nothing bad happened....about 10 rounds of spark plug changes with the battery connected, one instance of the car running with spark plug wells filled with water, nothing bad happened...methinks that something would only happen if you have a major karmic imbalance coming down the pipe for repayment. might wanna try a stronger fuel injector cleaner like bg44k if your trying to troubleshoot a lack of power, that is, if you aren't having it professionally done somewhere else. when it gets to 95 here, i find that nothing makes up for the lack of power.....and i suspect that a local gas station might be running 90% fuel.....i wouldn't be surprised with the prices the way they are...cars won't even (noticably) burp with 80%, surprising to me.
