hey guys, my cars been sitting for 6 months, never started it czu the tranny was out, anyways put a new tranny in, fired it up, drove it home, and its lacking bigtime power, idles rough, but if you set the cruise at 60 or whatever going down the highway it will just purr along, untill you get to a hill when it needs more power, but anyways when i took my exhaust off i snapped two exhaust flange bolts on the right side and couldnt get the remainning stud out, so my exhaust on the right is hanging on by one bolt(never thought it would be a problem, since i will be putting headers on in a while) but i was thinking since the 02 sensor is RIGHT there by where its leaking could the sensor be picking up the oxygen from that leak and creating it to think the cars running lean? then it richens it up tons, making it run the way it does? another guy told me since it sat for 6 months a fuel injector could have gotten plugged up, but i put stabil in it last fall and ran it through all the way, well anyways, any ideas??? anyone have similar problems? let me know thanks guys!!!

 

oh yeah also i think the car is really using a lot of gas too, seems like im gettting very very low milage, makes sense if it was running rich then, also when i did put that bolt in for the right side it did make a tight seal, but i suppose by the time the engine vibrates it kinda opened up, well anyways, hopefully someone knows somethin!

you need to fix you exhaust leak first. The exhaust leak is messing up your O2 reads.
