hey guys my car recently was running like hell it was surging,and missing and popping. i found out it was the wires two were burnt from the headers and one was cut from the belt and also one plug was half way out, so i fixed that and the car stoped having those problems.but it has a serious lack of power now and has a very strong gas smell from the engine bay and the exhaust.what could be causing the lack of power, o and also its not thowing any codes.

 

if it has a gas smell it could be way too rich, although I'm not sure why the engine bay would smell like that. maybe you have an exhaust leak.

 

what would cause it to run to rich 02s?

 

a lot of things can cause you to run rich

vacuum leak/exhaust leak
bad injector(s)
bad tune
o2 sensors
map sensor
fuel pressure reg.
etc

 

jay, do you have LT's???

 

no mids.

 

even with mids you still may have to do the heated O2 conversion. have you done it yet?

 

Scanmaster, datamaster, or Freescan would do wonders in helping you figure out what's going on and help you rule out certain things.

 

nope maybe Ill have to talk to sean about getting a kit.and would it running to rich cause to have lack of power?

honda hunter-I already did the flash scan and got nothing.

 

You would be surprised how much power is lost when youre running to rich. I was reffering to something that could datalog and show your o2 milivolts etc.
