[Limitz]

I used Techron complete system cleaner today when filling up an empty tank, it’s my first time using it and I have 102,000 miles, when I finished filling up on gas I turned the car on and let it run for a good minute then started driving home just fine for about 5 minutes and then car started losing power and went into limp mode, pulled over put car in park and car turned off on its own. I then turned it on and noticed it was sounding a bit different (had a cammed sound to it kinda)left it on for about 5-7 minutes the noise went back to normal and then drove it home but once again went limp mode and just drove idle home. Which wasn’t that far. Any idea why this would happen ? I thought it was safe to use, my only guess is that I have high mileage but I don’t think it would be bad enough to make the car go limp mode, also NO check engine light or anything turned on. Tried turning the car on next morning and it just cranks now. Note: before adding the gasoline the car was running fine no problems took it on a 30 mile trip right before filling up with gas which just makes this more frustrating
