my cars slow?

My car runs boggy in first and second gear. I mean REALLY boggy. I'm guessing a stock anything could beat this for real.

I run a 91dx hb with a b16a motor swap. The vtec works fine, the motor sounds good, but I'm just not sure what the problem with the start off is. It sucks horribly. any ideas? The only problem I know of is the computer flashes 1 red light when I turn it on and that is for the 02 sensor which I don't know if it would cause my car to run SLOW in first and second??? any way thats for the help in advance!

are you talking about bogging off the line or about the motor not pulling hard to higher RPM?

Having a failing O2 sensor will make your motor run rich if anything.

yea I'm talking it doesn't pull hard.. hell it doesn't pull hardly at all :\ and it sounds like it's not getting fuel or its getting to much and choking it out .. you know how when you choke a dirt bike and it runs mopey for about 10 seconds? well same shit here man I dunno but it does it 24/7..

My car would bog really bad when I had the o2 sensor out when I had a test pipe on check all your conections make sure your sensor is in nice and tight.

If your O2 sensor is not working than your engine is running on a "limp home mode".

awesome I hope thats my problem :)
