Default problems!!

seems to get better after the car warms up for a while, but it seems like my car wants to die, hanging around 500rpm and a little under. then i tap the gas a little, and nothing. then all of the sudden it revs up. even if i hold the gas in 1 spot, it'll fluctuate up and down. i read about other people with these problems but i can't seem to find them. when i had my car idling for a while, i started hearing a knocking on the passenger side, i could hear it best when i put my head up to the front tire. then a lil while later it was on both sides. since then the knock hasn't come back. i checked my oil and it was perfect...surprisingly. i'm usually low. did my spark plugs take a dump already?? i thought i had a valve seal leak, so i thought maybe that would dirty up sum spark plugs...but my car is fine after it warms up. i have o2 simms, so i don't think its a faulty o2 sensor. maybe sum bad gas??????

Look at the wiring on both the front o2 sensors. Look for burns or freys.

So you do have simms in place of the front o2's. The simms are for the rear o2's for when you take out or gut the cats/ ory pipe. You need to have real o2's in the front.

The fronts should be on the header collectors.

i just looked at them, the outside black part was frayed, so i opened one a bit and then a yellow/orangish wire started pokin out that looked like it was cut. it too was frayed. are 02s easy to put on?? it looks like you just unscrew the thing and connect to the other wire harness. i think i'm gonna wrap electrical tape all around new ones just to keep them from fraying, becuz both sides had holes in the outer black part

You can buy a o2 sensor socket at advance,auto zone etc..., It looks like a deep well socket that has a side wall cut-out for the wires. Its a pretty easy job. So I take it you found the front ones.
