Yes the check engine light is on. I just ordered a new A/F sensor and an oxygen sensor. If replacing those don't work, do I need a new timing belt or coils?

edit: my friends told me they can see and smell gasoline coming from my exhaust

 

But is the light flashing on and off or is it just lit up solid?

 

the check engine light is solid from the P0171 code. the rest of the codes are pending.

 

Have you tried clearing the codes out and they still come up pending, especially with regard to the misfire codes, the P03xx?

 

Yes I cleared the codes and they still return.

 

A few things came to mind with those codes. One thing I would do would be to take the 3 coils in the rear and switch them to the ones on the front. If you still bring up those codes, you are talking about perhaps some clogged fuel injectors on the rear bank and that's more likely than another very remote possibility, a gap issue with all 3 rear plugs (doubtful). The rear A/F sensor may get some cleaning if you toss in a fuel injector (there might be some carbon buildup given the misfires occurring) and that cleaning that out may clean up the system. I'd really have to see what kind of readings your getting on those a/f banks (that's what I'd be doing if it weren't the ignition coils).

 

I'm waiting until I install my new sensors before I mess with the coils. I think the new MAF and A/F are throwing off the old sensors because the misfiring cylinder codes never came up until I replaced the MAF.

 

I'm replacing the o2 sensor right and I am having a hard time unplugging it because it goes under the carpeting underneath the seat. Can someone help me or is there a guide somewhere to do this?

 

i found a small hole in the carpeting but it is not really close to the plug, should i just cut the hole larger?

 

If you need to get in there...cut. A friend of mine had to do it on an RX300 belonging to a friend not too long ago.

 

I cut a pretty large hole and it worked. 2 new a/f sensors, a new maf, and a new o2 sensor. if any more cel codes pop up im going to be so pissed.

 

encountered another problem, this time the driver seat wont move, the lumbar support moves but the seat and back rest don't. i tested all fuses, what should i do?

 

It happened after I took two bolts off the back and lifted the seat forward so i could cut a hole in the carpeting.

 

Are you actually trying to remove the seat (forgive me if I don't read everything right above) and how many bolts have come out?

 

I found the problem, I actually cut through some wires when I was cutting hole underneath the seat. everything works fine now. Thanks.
