worries about my 2000 GTS
well, it's really 1 worry and 1 question. My worry is why does my engine rpms jump from 1500 to 2000 back to 1500 then back to 2000 over and over for about 5 seconds when ever i start my car in the cold. Also, i would like to know why i can't go past 7000 rps and my vvtli won't kick in if the engine isn't warmed up. confused

it's called don't blow your engine up... you should NEVER gun your engine when it is cold, the celica will stop your RPMS till you are warm. never gun that car when it is cold dude... the random reving.. um dunno ask a true celica owner. i just know the car does not allow you to go into lift if the engine is not warm, it's normal

if you'd like to see 200,000 miles dont be hard on your car until it's warmed up

Are you turning things on like your heater, lights, etc. when you turn on your car?

The ECU controls idleing level, and when your engine is cold it likes to keep it a little higher. When you turn on your lights, heater, etc. the RPMs tend to dip a little bit, and then the ECU will try to adjust for it.

when i start mine up in the cold it jumps a few times...but it's totally ok after a min or two...and yeah if your engine isn't warmed up...you cant rev too high. It's good toyota did that so overzealous bastards don't low their engines rofl

and i wasn't making fun of everyone besides us guys in general... wave

1) your IACV is dirty. refer to the garage installs engine forum for the writeup I made on how to clean this properly. It shoudl solve your idle problem.

2) there is something called a neutral rev limiter in our cars. it kicks on at 7,100 rpms. (if you were to put you car in nuetral and slam the gas down, you'd bounce off that limiter nad never get higher.)This limiter also get tunred on a few other ways.
a) when the engine is cold
b) when in nuetral
c) when you get too much wheel spin. (the ecu goes into a safe mode thinking your car is free reving when really you're simply spinning th etires too much, too fast.)**this typically only happens on hard launches when racing**


hope that helps thumbsup
