Cold Cylinder! Help!
Cold Cylinder! Help! I have had one cylinder running about 60-90 degres f less than the others. I am using a temp gun right after the header flange. Here is what I have done so far: replaced fuel pump, replaced spark plug( was white tipped so running lean), swaped injectors(cold cyl. did not follow injector), and checked for any leaks. The other spark plugs look fine and I am not getting any codes thrown. This doesnt make sense... any suggestions?? Car also goes "flat" early in the drive around 2800 RPM...
i know this probably sounds stupid but when my o2s went lazy my front cylinder on passenger side was 40 + cooler than the rest.new 02s cured the problem and i still don't know why it was only one cylinder.
interesting...I recently replaced my drivers side o2 to cure a SES light but maybe the other side is bad too, I will try swaping the new o2 over and see what she does. And yes I did try swaping plug wires and replaced the bad spark plug.
