Does this make sense or m I just loosing it...My b16 runs shitty when warmed up, no codes er nothing, just, once it warms up it feels sluggish like a dog...so will colder plugs make a difference?
Thanks in advance, any insight is helpful!

 

um. no sir.

very odd, as the car should be a turd till its warmed up lol.

wish i had a better comment than that for ya, but i couldnt tell you without takin a look personally

 

what do the pkugs look like that are in it now lean rich?

 

this is just me but if it is running sluggish I would say it is running rich or not combusting enough, so cold plugs would make it worse. Keep in mind that alot of engine management like o2 sensors don't work or effect the engine till it is warmed so are you sure your cel works.

 

Yea like joelmatt89 said, the car is in open loop which means the car will run fine cuzz it doesn't see any problems yet, but when it warms up to OP temp the car has finished and ran into closed loop and you could have a bad sensor, most the time if it runs like crap check the coolant temp sensor cuzz if its off its like a o2 sensor it will screw up your air to fuel ratio

 

werd, cold plugs are to make the fuel not light as easily. for example, if you're running nitrous, to help prevent premature detonation (thinks of american pie lmao)

 

If the car was running fine before and now it's not, IMO it's not plugs.

PM one of the tuners in your area and see if they can do some data logging of your ecu and see if there's something wrong. Check out the top of the Forced Induction forum, (sticky)
