Just got done putting some in. Trucks is much better, doesn't stumble when i nail the gas like before. But now after about 1 minute of idling it starts the upa dn down idle. It didn't do this before, and now it does. By up andf down i mean it will ide then down like it wants to die, then it comes back. Almost like a supercharged motor. Ther lope they have. Any suggestionsas to the problem. I am thinking IAC motor.

 

The cleaner might have effected the o2 sensor as well if not o2 safe.

 

Well, i thought that since it was Mopar brand and everyone i talk to hasn't had any of those problems then i wouldn't think it would be it. But the last time my O2 went bad the truck woul stumble badly when ever you would jam on the gas and it isn't doing that. The can didn't say anything about removing it.
