how many peoepl have a slight miss on there supra aka the fart or the cough

[Jeff Lange]

my car did it for a day, if i started to boost hard it would begin to miss.


all it needed was the old GReddy spark plugs pulled and some new OEM ones from toyota to get it running silky smooth again

Silky smooth and ugly.

(Also, you have a 1JZ, and that wasn't happening at idle... so you don't belong in this thread.)

mine was very smooth until i went to full 3in exhaust. specifically after the cat-back i got a slight miss at idle. {shrug} never bothered me that much

Mine is very smooth most of the time. The only time I notice any type of roughness/shake is during the short time (10 to 15 seconds) of transition between open/closed loop. This does not concern me at all. It's just me being anal. 99.9% of owners would never even notice it.

look into the 2JZ COP conversion, people have had good luck with it getting rid of that miss.

Transition time? What are you talking about?
