7MGE: Smoke/Mileage/Cold-Start

SupraDupra · 07-09-2007, 07:05 PM

I'm thinking the cold start injector is running on the rich side. When is the last time you did a general tune up? Is the car giving any error codes? A tired oxegen sensor can also give you crappy mileage and throw off the air fuel ratio.

Personally, I would start with a compression test to make sure the headgasket isn't leaking.
