After weeks of scratching my head at what was wrong with my idle i think i fixed it last night... The problem was occasional back fires and miss's at idle, and when i would go into boost the car studdered and felt bogged down like a ****. I changed spark plugs, wires, the coils to no avail... While standing at advanced i decided to go ahead and change the O2 Sensor.. Advanced list's the OEM O2 for 125 bucks. And a universal that requires you to splic in your old o2 harness for 15 bucks. ( guess witch one i picked ) anyhow, After replaced the o2 sensor... BAM! car idles like glass now.l and pulls like a dream again! .. so everyone experiencing my symptons, Go spend 15 bucks for a Universal o2 sensor. best 15 bucks ive spent yet

 

How many miles are on your car?

 

62k now

 

Yep, you can save $100 just by splicing one wire!

For anyone with a PFC, turning 'O2 feedback' OFF is an easy way test for a bad O2 sensor. That's how I found out mine was bad.

I got a BOSCH #11027 for around $20 at Autozone.

 

same one i got. or my was the 11012.. witchever one was universal.

 

whats a pfc?

 

Apex'i Power FC. Basically it's an expensive (I'm a cheap bastard) stand alone engine management system used for when you do a lot of modifications to your car. It controls fuel, timing, ignition maps etc.
