hi i have a ef9 running a b18c converted from obd0- obd1 any way recently there was a skunk 2 intake put on to it now ever since maybe its nothing to do with it but the car would start then you would bring it for a spin and all of a sudden it would start to shudder then when you slow down it would cut out and not start back up then you could leave it a while and it would start up again also its not reving past 7000rpm any more and has thrown up a code 43 once which is a fuel supply problem any ideas what could be the problem
