Sup guys. I recently got some work on my car done and I think the technicians reset my ECU. The car isn't perorming AT ALL anymore. I'm considering resetting the ECU this weekend. I know how to reset the ECU, but how do you drive it after you reset it to make it perform better?

The car isn't perorming AT ALL anymore.

What do you mean? Like its not running? Im sure youve already thought of this, but if I were you Id take it back to the place that did the work, they should know whats goin on since they messed with the ECU.

After it's reset, start the car and let idle until fan comes on then off. Do not touch the gas pedal & make sure all elec. is off.

If you just had work done, I'd take it back.

It's just not pulling hard. Like it won't accelerate like I know it can. They changed the oil and filter and also replaced the regulator in the window. I can't just go back and say "you made my car slower". I thought there was a certain way you had to drive it for a little while to get it to remain like you want it.
