Cold start issue

[dan_ep82]

hey, every now and then my GT fucks about when starting from cold,

it starts right up but idles really low and runs on 3 cylinders and wont rev for about 10 secs then picks up and is fine.

its only started doing it since the cold weather kicked in any ideas?

take some fuel out gaz car bearly ran on your map

yours is the only map iv seen thats had that much fuel added low down

Mine does this when I go to start it and only flick the key a little.

Then when you go to fire it up, it takes longer than normal on the key then runs lumpy for 2-3seconds.

It's just the cylinders gassing up

it could be ur ect sensor its the one that controls the colk / fueling i had the same problem replaced this sensor and its been a1 since

Making it run uber rich?

Would this issue still occur with a JAM Ecu?

The fueling is fine down low is leaned out as far as the EMU can take it
