alright well i got a new valve cover gasket, cam sensor and cam seal on my car and my mechanic said he fixed the broken wires going to the O2 sensor..but now i have no power under 2k rpms (like even if i floor it i BARELY move)and the exahust is like bvvvvvvvv..(hard to explain the sound by typing lol)...once i get above 2k its better but runs crappy...im thinkin its my 02 sensor..im gettin a cell 12,21,31 which would be (discarding 12) 02 sensor and cat conv...correct?

did you pull the o2 sensor out or just fix the wires? did he wire them back correctlly? Try pulling it out and seeing if its all carboned up

i dunno..im not really a mechanically inclined person at all lol thats why i come here..but the mechanic that fixed it sucks (today was the last time im ever goin to him)..he said he fixed the wires and nothing else about it..although when i asked him how it was runnin (it was bucking when i gave it 2 him) he hesitated and said "oh well it seemed fine to me when i was in it"..so i checked the miles and it didnt move..so tomorrow im taking it 2 a diff. mechanic...one a lil more expensive but that i know has a good rep and does good jobs...so im praying to god its only an O2 sensor b/c i just put over 1k into the POS in the last 3 weeks..and its funny..b/c i stopped paying it 3 weeks ago 2..dam car paid off curse

I think the mechanic knew your mechanical apptitude when you walked in the door.

Its REALLY easy for a mechanic to take you for a few hundred to thousands of dollars.....for nothing.

Def find a good mechanic or buy yourself some tools

wait, who was the one that messed up the wires on the O2 sensor to begin with??? anyway definetely find a different mechanic, and get the codes cleared, the O2 sensor code might just be there from when the wires were messed up. Also a clogged cat will cause you to loose that much power, so check that out. AND that mechanic is the biggest idiot i know now.

well the guy i go to know is one of my friends brothers so i never really thought he would try to screw me..i dropped the car off to him w/ no CEL 21, came back and there was but he said he fixed the wires (free)so i dunno why he'd do it on purpose..unless he actually didnt fix it and is waitin for the shot 02 sensor to screw the cat up maybe?..the other guy is a friend of my dads and had bled my clutch twice for free to buy me some extra time w/ clutch problems i was havin..so hes my new guy

i really gotta learn about all this crap over the summer

CEL 21, replace your O2 sensor as the heater + might be screwed up.

replace with real Mopar (NTK) direct replacement.
