Problems Once Again...

[MyStangStanks]

As you all know, I had a bad O2 Sensor. Well, I changed that yesterday. I know that I need to get a scanner so I can reset the codes to get rid of the light, but that's not the problem. I floor the accelerator pedal and there's practically no throttle response nor acceleration!! I'm thinking to put the old sensor back in so I can get up and going! Does anyone have any ideas as to why this is? Thanks in advance - John

try disconnecting the battery for a bit, reconnect it and try again

Yeah that's what I was told on another board. Thanks for the feedback. I'll try it tonight.

The same thing happened on my car! I removed the throttle body and used some carb cleaner to remove the black grime inside. It takes some massive scribbing but improves throttle respone greatly. Otherwise try to get a scanner.
