Well my bad news got worse last nite as on my route home from my flat a mini bus scrapped my bumper

bit gutted man as its stripped the paint and creased my lovely rust free!! drivers wing. The guys claiming it was my fault but it wasnt my car was staionary so in theroy he scrapped his mini bus on my car. ill post pics up wen ive got bit more time.
The car is now wat feels and sounds (whilst driving) like its cutting out at low revs so as i push the accelarator the car just become unresponsive as if the theres no combustion. ive checked all the spark plugs they seem fine usual tan/grey colour, the leads all seem normal. the car cutting out could it be due to under fueling?
ill get my dad to help me with the compression test and see if the rings are worn. Is it common for piston rings and vavle stem oil seals to go with a car with a resonably low mileage?
how would i check the turbo seals?
And while i remember Scoupe i get around 240 odd to a brimmed tank without caining it (because i cant coz its pinking)
Thanks for the help guys i hope i get this fixed as my silvias my daily driver I need it for work etc thanks again
