i have all kinds of power but its there then it bogs then its there ect. im thinking downstream o2 sensor, ran the check engine code and it was that sensor and it said short to ground. any other ideas?

 

Could be alot of things. What was the actual code?

 

If it indicated the downstream o2 I would start there, either the sensor or the wiring. Always fix what you know is broke first.

 

the specific code was the downstream o2. i know that it said that it shorted to ground. i replaced the fuel pump and it helped alot but i still can't get more a quarter throttle before it nose dives. haha. i'll fix the downstream o2 and see if that does anything. probably ****ed it on dirt roads or snowbanks. ill let you guys know how it works out thanks.
