04 GTO sluggish! need help! Asap!

hey guys i recently just bough an 04 goat with around 22,800 miles and its driving like crap now. i havent had time to take it anywhere, or the place that i bough it at. but when u turn it on the engine with drop to almost 400 rpm then shot up to 900 then drop to 500 untill it finally settles at 900... and when ur driving it and u give it some gas it just bogs down... like when u turn a Lawnmower on and put it on the choke. i took it to autozone to check the ecu and it said that the O2 censors have low voltage and the system is too lean. now the guy who owned it before deff had a charger in it and im thinking that the ecu is programed for the charger and the air/fuel ratio is messed up. and that would explain why im getting 9mpg. another thing that i just noticed was that when u turn the car on it welcomes u with the holden logo not the pontiac... and ohh the check engine light is too.

thanks guys i really dont know wat to do and really hope its an easy fix and that i can enjoy my new baby soon... a friend of mine said its on "limp" mode w/e that mean but idk.

thanks...

Hey welcome aboard.

Sounds like you've got some very strange things happening to your car. It is regularly supposed to be idling at about 900 rpm. The Holden logo is no big deal, he had someone program it into the system. Your just lucky he didn't program his name into the system. I doubt the car is still under extended warranty? Can't really help you much more, Goodluck with everything buddy.

Welcome to the forum.

Thats really messed up that he did that sh*t. Ive never heard about programming your name to it.

Im thinking the car haves a very bad tune you should take it back to the dealer and find out what they sold you.

Pray the car wasn't tuned and passworded. If it was and it cannot be unlocked don't settle for anything less than a new BCM and have it set up by a Pontiac dealer, courtesy of the place you purchased the car at.

You should have gotten some kind of a warranty.

A BCM from the GM parts warehouse shows List 254.70. Your price 188.73. The place you purchased the car from is on the hook don't let em off.

Give em a chance to fix it, if they can't DEMAND they take it to Pontiac and have them do it.

thank you so much man i deff tell him about the bcm... i dont think they will even know to look there if i dont tell them.
but do u think its deff an electrical system? nothing mechanical or anything i should worry about?
and the funny thing is that when i test drove it it was fine... it drove like a champ.
so weird that when i took it home it did that.
