huge problem
 

well i tryed to install a s-afc to just so if it would work like only hook up the power and the grounds, well i start my car up and it idled really low lil 400 and it runs super super rich, so i un hooked the wires and it still does it, such a huge power lose at crusieing feels like a cylinder is out, but under full throtle the car is fine but backfires lil a crazy, and the car dies out wheni come to a stop, kinda feels like when u drive with out that egr hose on or w/e hose that hooks up to the intake, well so i have no clue what this is , and my car run awesome b4 this, so this suks, ne help would be great thanks

O2 sensor? EGR messin up? Is the check engine light on?

no check engine light, but i dont understand it was fine b4 i splice the wires

:dunno: Im not the best for this, hopefully someone else is haha

i replaced the o2 sensor nothing, still running way to rich, could it be sumthing wiht the ecu

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
