Normally if I hear a thump coming from a car of mine, it means the hooker in the trunk needs to be knocked back out.

 

Just wanted to give you guys a update. I found the culprit to what was causing that noise. My wife came home from work one day and said her check engine light came on. I asked her to stop and have it scanned to see what was wrong with it. Ended up being the O2 sensor thats under the car. I brought a new one and when I went to replace it, I noticed the old one was already loose. I put the new one in and tightened it down good and the rattling went away.

Never thought to check that, but that took care of the problem.

 

Stupid thing. Oh well, I'm glad you got it sorted anyway.

 

motor mount(s) for the thud, your throttle body plate is dirty and position sensor. prob the main reason your car lags

 

damn I wish my o2 sensor was loose I can't even get it out...and I got a new wideband coming.....

 

Spray with penetrating oil (NOT WD-40) and let sit. Tap with hammer. Let sit. Hours-to-days may be required. Tap wrench with hammer in the TIGHTEN direction first, then in loosen direction. May have to heat the pipe (with a torch if the car won't run).

 

Interesting, days. well I got my wideband today but won't be installed till summer. You think just with a heated engine it would work eh? ANyways don't want to hijack thread. good day sir.
