First off the car was running well, so I tried to put in a wideband in it and turned it on and it only cranks but wont start all the way. So I took of the wideband out and put it back to the same way it was, well it did the same thing it cranks but wont start all the way. Can someone tell me whats wrong with it? Would it also cause to erase the old tune it has on the ECU? your help would be greatly appreciated thanks
