miss fire problem
 

hi all
ive managed to get the engine into my v reg 2000 grand voyager
the engine when it came out the other car had a slight miss fire which i was told was a engine managment problem

ive now got the engine in mine and even tho i aint got the exhaust on there still seems to be a slight missfire

does the fault code test witht the ignition key work on my v reg 2000 grand voyager

thanks
