Someone mentioned in another thread that a loose wire connector to the coolant temp. sender or even a bad coolant temp. sensor could cause poor mileage....

If that injector cleaner generated excessive smoke, it could have messed your O2 Sensor again. Then again, I have never used it so..

Techron is good stuff and incredibly safe, unless the injector is simply too dirty.<but> if an injector or two are done for anyway it may worsen symptoms on occasion.

If the cleaner knocked something loose and now its keeping the pintle from operating properly an addtional application might either hurt or help things.Difficult to predict.

maybe you dont have this problem but maybe your tires are underinflated
