when you spliced into the wires did you short something out. Im just asking because i was helping a friend out one time installing an A/F guage and he spliced into the O2 sensor wire, when he did that he went through the sheilded part of it, the wire uses a ground sheild, much like an antenna coax cable, and it made the car run like poop cuz it grounded out the signal to it. You might go through and check that out

so how do i check for this becuz i opened up the ground and just wired back together and taped it up, with electrical tape,

ok well me and the pa where looking at my car well, he felt the injectors and told me that once the car is on they say on just dumping fuel into the car, ne one know if there is a fuse for the injectors or how to correct this problem
