Misfire when first starting up(cold)...BAD!!!

[jonnyd]

This is my first post....

I have a BAD problem with a misfire when the car is 1st started. No check engine light no fault codes, I checked. It will buck and fart till about 1200 rpm then the turbo spools and goes. It will have a loopy idol for a while then be fine. Any ideas?

Sounds like you just need new spark plugs or wires. Maybe coils but Id check the plugs.

if he had a ignition issue it would be worse under boost, not start up..

maybe you should do a compression test to see if you might have a bent or burn,t valve .good place to start for how long it takes
