Ok this might me kinda wierd, but I had to make an O2 extension for the passenger side header. When it rains my car runs like crap(bogs down and idles rough) and i wonder if water getting into the conections of the o2 extension i made would cause this. Also after my car is up to hottest normal temperature and i turn it off and drive it within the next 20 minutes my car stumbles at idle for the first minute after startup.Any help would really be apperciated. Thanks

 

I would think you should just go anb buy the pre made 02 extentions from thunderracing.

If you can try to get it scanned and see what the o2 readings look ilike, Also if it is messing up in the rain it is probly going to put in some fals reading and they will affect the Long Term Fuel Trim of the car making it run worse later even after the the 02 are working fine. Try reseting the PCM's memory by pulling out the PCM fuse for about 15 seconds and see how she runs after that

 

well i already have an extension on the way as well as 2 new O2 sensors.

 

well them just remember to rest the pcm after you install them and see how it does

 

Which one is the pcm fuse? sorry if that is a stupid question.
