Hey, I need some help with my prelude. It's running way too rich which is making it hard to start, The exhaust is super thick, and it seems like it cranks faster then it should. Where should i start at fixing this, ive replaced the Spark plugs and wires so far. Thanks

 

o2 sensor?
clogged or stuck injectors?

 

If maintenance doesn't cure you, just tune the A/F ratios.

 

Oh yeah ive also replaced the Oxygen Sensors, but i have Pacesetter headers so one of the sockets threads were screwed up which made the Sensor a B*%$# to get in could that have anything to do with it?

 

If you damaged the O2 sensor, then yes.

And I would check the catyletic convertor as well.

 

How do i check the cat?
