7mge rough when cold

[supra_cam]

For the last couple of weeks my 7mge has been driving rough when cold until it reaches its normal driving temperature then its suddenly drives normally. Not really sure where to start looking? Its not bothering me too much at the moment but I would rather check it out incase it gets worse.

Maybe try checking for codes, and possible coolant temp sensor, rooted

7mge's have a cold start injector, id check that ;-)

My cressy did this when it was auto. As soon as i converted it to manual this went away. Strange.

My 7m(gte) did this, then I realised it had a BHG So that may be a possibility!

If the engine is also hard to start, yes I would look at the cold start intector time out switch. If it starts well, then you have other problems.

cheers Chuck.

I doubt its a bhg, i've already fixed that crap. Ive checked the codes and it comes up with the TPS, but i'll also check that cold start injector and coolant temp sensor, thanks for that. My mate thinks it may even be the fuel filter? Hope not, 'cause there in a bit of a tricky spot to get to!

[abently]

Its definitely not the Fuel Filter so don't waste your time or money on that.

you did the hg but did you use arp studs and metal head gasket?
