cold rev limiter
 

Is there such thing as a cold rev limiter on a pg7 ecu. Because my car won't rev over 7000 rpm after I step on it and it gets cold.

im pretty sure there is yes

but its only on until your car warms up from a cold start

has nothing to do with the weather outside

Re:cold rev limiter
 

Shouldn't be reving that high till the motor is completely warm anyway!

I am having a problem were the engine cools down at hight rpm, then warms up as soon as I let off. And I think this is causing the cold rev limiter to kick in. It cools down to about 150.

maybe your thermostat is stuck open ???

Re:cold rev limiter
 

already replaced that

Re:cold rev limiter
 

maybe you put it in backwards? (is that possible?)

if you are cooling down too much, your thermostat isnt doing its job, hands down

Re:cold rev limiter
 

I think I put it in the right way because I payed attention how the other one came out. Could it be the water pump?

Re:cold rev limiter
 

Water pump cant push the water past a closed thermostat...

maybe there is a little gremlin inside your motor makeing it act funny....( is that possible?) :P
