Okay, so i recently had my check engine light come on, i hooked my scanner up and it showed P0132.
So i ordered a NTK Upstream Oxygen Sensor and replaced it. At the same time, I went ahead and took off the throttle body and cleaned the IAC and throttle body itself.
I cleared the code and took it for a drive. About 5 minutes into the drive it started loosing power, RPMs dropped, and it started jerking and "jumping" back and forth. I pulled
out the scanner and now it read P0132 & P0135.
So i had it towed to my local shop. They told me I "Put the O2 sensor in wrong" and replaced it with a Bosch... (Yeah I know).
I picked it up from the shop and it drove fine.. However the CEL was still on. I pulled P0132 & P0135 again. But it wasn't bucking and jerking down the road.
So I took it back again to have them actually fix what they were suppose to. They told me that they ordered 3 different O2 sensors (Another Bosch, Denso, and NTK) and they still couldn't get the CEL light to go off.
So finally I decided i'd just take it back for now and try to figure it out on my own. Well, 5 minutes into the drive home, it starts kicking and bucking again. I loose all acceleration (unless my foot it BARELY on the accelerator) and it cuts out on me at a red light.
I pull the codes the old fashion way (turn key on-off-on 3 times) and I get P0505 & P0132.
I have a feeling it's not the O2 sensor now, but might be either a clogged cat or maybe the IAC is shot.
Any suggestions or ideas?
