S4 T2, Some times starts. some times doesnt start???
 

Ok I just replaced my front seal, when i got the car all back together it started fine drove great but didnt do the warm up thing like it usually does when you first start the car idle went straight to 800 rpms, parked the car for about 20 mins or so went to leave wouldnt start! tried it again in an hour or so started right up, started all day yesterday but it starts and idles at 800 rpms, but still no warm up. wouldnt start again last night so while cranking it i gave it a tiny bit of gas and it started. whats wrong???
