long story short:

dropped my work light in my engine bay and it touched the positive terminal on my battery and my K&N intake tube, saw sparks, now the car runs like crap, runnin through gas like its going out of style, stopped and got codes read, o2 sensors bank 1 and 2, 2 codes for running too rich, changed the maf sensor, ran good for about 20-30 miles, back to being bogged down, the engine is obviously not getting enough air, what do you think?

 

I would reset the battery first, Check all your fuses in case you burned one or maybe a few out.

 

done and done

 

headin over to autozone to get my codes read, ill let ya know whats up when i get back

 

p0172 system too rich bank 1
p0175 system too rich bank 2
p0037 ho2 bank 1 sen 2 heater circuit low
poo57 ho2s bank 2 sen 2 heater circuit low

 

What car is this ? the rx300?

 

oh man im sorry, my fault, no the 2003 IS 300, sorry, im used to being over on ISFanatics where its all IS's lol sorry man

 

Ok, For your k&n intake do you have the heatshield that came with it ? If not put your stock airbox back in and reset the computer ( unplug the battery ). If that does not work you might as well change out your 02 sensors; Hopefully you didnt spike the ecm and causing it to malfunction. So try this first

1. install stock airbox reset ecu if that doesnt work
2. switch out ecms with someone else who has the same year

Btw. What were you doing when you dropped your light on the battery ?

 

thanks for the help, I jacked up the rear of the car and noticed the left rear hard line was rusted and leaking, changed it fine. after pressure built up right rear line broke also and started leaking, got too tired so doing that tomorrow.

 

I'm new to this forum. My Lexus suddenly won't start either. I had the power steering bearing and belt replaced on my 2000 GS300 two weeks ago after the thing locked up. I don't know if what I'm about to write is related to that issue, especially since the car was great after that $600 fix. This morning, however, after sitting in the rain all night, the car won't start. When I turn the ignition key there's a little click, the lower dashboard lights pulse and flash and there's a rough vibrating-drumroll sound. After I return the key to the off position the dashboard lights up for a second, and then it's off. The battery seems fine, as I can turn on the headlights, and the car drove beautifully last night. I don't know what's going on. I've never seen this reaction to starting before. Any ideas? Thanks.

 

Now it's starting. Very strange. I'm wondering if something that shouldn't get wet became exposed when the power steering work was done.

 

Change out all the lines. Your better off.

 

Check your battery terminal connections if they are loose. Also look around your powersteering pump to see if anything was crimped or loosely connected. Check your belt tension; You should have a small deflection in the belt when you move it up and down.

 

ok so heres how it went over the weekend, replaced the o2 sensor on the y pipe, replaced the throttle position sensor, reset ecu, running a whole lot better but still not perfect, idles well, runs fine, doesnt run rich or at least not like it did, if i gun it though it chokes

i was replacing the battery when that happened by the way, im havin the wifey take it to toyota today for a diagnosis

 

When you replace the TPS you need to get it calibrated!! did you calibrated?
