I was wondering if it would be bad if I had the first 02 sensor(on manifold) plugged but the second 02 sensor(before catback) not plugged. Do you guys think that my car would flood the motor with fuel cuz it thinks that it is getting more air cuz of the outside temp. The reason why i ask is cuz the dp has to be cut like in the middle so I can get it to fit and then I have to go to the shop to have it re welded. The shop is like 5 miles away. Thanx in advance.
