Gtr Runs Like A Three-legged Billy Goat

[SiR_RB]

just checked the old plugs they are NGK R had abit of time so i just put them back in, started the car and went around the block, car hasnt been started in 1 week and it ran perfectly !

il keep an eye on it in the coming weeks hopefuly this was the prob !

OK i have exact same problem, R32 GTST RB20DET nistune ecu gtr injectors z32 afm plugs gapped to .8mm hks turbine

Car goes into cold start mode, id love to make a vid on how the motor behaves when starting cold, and i will, WHEN IT STOPS RAINING!!!!!!!!!! grrrr

I start the car (dead cold morning) starts fine, revs well, 30 secs or so after start it clicks into this "Runs Like A Three-legged Billy Goat" mode! NOW i thought it was something to do with the O2 sensor, bought a new one, no change. Coughs misfires under load generally runs like poo, I unplug the O2 sensor, no coughs or misfiring but now surges under load, n same as everyone else this mode clicks off when temp guage hits the middle

Not everyone has this problem i see n id love to find out how to fix it or help fix it!!

check resistance of your water temp sensor (both when cold and hot)

if unsure just change anywayz its not that expensive

also make sure you have the correct sparkplugs/heat range...this was the prob with mine believe it or not

I will try to get a multimeter to check coolant temp sensor but now you got me thinking its the plugs lol I recently put a new engine in the car but it was doing the same thing with the old engine, im running brand new DENSO K20R - U11 spark plugs atm gapped to .8mm but the plugs that were in the new engine were NGK-R PFR5A - 11

what would be the correct plugs for my application?

Ok so i have an update, turns out its the O2 sensor thats stuffing up my cold start and idle. I unplugged it and everything is fine again, (btw the O2 is brand new)

So im guessing my ECU was tuned with the old stuffed O2 sensor and now the new one is leaning the fuel mixture out too much.

cant figure out why its affecting idle tho.

This is probably a stupid question but where do you get the CONSULT hardware and software ?
