Just keep driving with the lights on eventually it'll go away

You are just getting a CEL correct not a CEL + oscillation?

[gwasabi]

Thats probably due to the Coolant just drive around for a bit and let the coolant settle. It'll eventually just go away

I FORGOT AND AM TOO LAZY TO REREAD DID YOU DO THE CHIP SWAP AND WHICH TB WAS IT AGAIN AND YEAR...

[gwasabi]

No I didn't do the chip swap I don't think kustom play did either

[Yoda]

Dammit mine started oscillating again and hard No CEL just hard oscillation like 1-4k rpm while driving.

Yeah I think I might do the same It sucks because on wednesday it ran flawlessly to work and back and then it just started happening again for no reason. I really want to figure this out and get it fixed though because there is definately a big power difference with it on. Did your oscillate randomly or is it like mine where sometimes you start it up and it runs fine but sometimes you start it up and it immediately starts oscillating?

unplug the battery for about 4 hours

chip swap the TB

do the coolant bypass

plug battery back on start car

wait about 5 mins to oscillation so settle down

step on the gas to make the car think your driving it, hold it at like 5K RPMS for about 5 mins (mine started to oscillate again, stopped let it settle and did it again for 2 more mins.

let car idle for 5 mins

shut car off, let it cool down for a few hours

open radiator cap

start car up wait for bubbles to come out and fluid to just about overflow then put the cap on, putting cap on should cause the coolant to come out at that point, wipe up spilled coolant.

drive around , my CEL went off then came back on the went back off but seems to be off now.

but i never had oscillating anymore using this system

I did the coolant thing but didn't let it overflow I'll try that. so 5k rpm for 5 minutes. Poor little car Oh well that bitch deserves it for doing me wrong by oscillating We need to arrange a Yaris meet so I can see your pink wheels

[PHXDEMON]

Also I don't see how the coolant thing could cause oscillation with the TB coolant bypass done. Anyone care to elaborate?

[gwasabi]

With a bypass it shouldn't oscillate if it is its just the Throttle being wierd

wait till I install my TB till you guys get a meet lol... (i'm just going to install after finals are over).
it seems like there's just 3 of us from phoenix on here
For the chip swap did you just use a new set of nuts and bolts?
and what did you guys do to get the rivets out?

That's awesome... On to the next CEL-inducing mod!
