Question about 1986 Jaguar XJSC

1 Answer

XJS V12, 1986. Loses power and splutters on hard acceleration

Drives perfect otherwise, put your foot to the floor and the engine dies even when not under load. Does not blow black smoke when spluttering. Some kind of fuel starvation?? Ideas please

    My 91 Jag XJS V12 was running fine then parked it and left idle for about 45 minutes then when I went to take off it lost its power and would fall on its face when trying to drive. You could sometimes rev it up in park but did not want to run in gear it would only idle. Now it wont even try to start at all. I checked fuel pump it has 90 LBS. pressure. New fuel filter. It has spark at plugs and I can here injectors opening. Please Help. Thanks

My 2001 tahoe loses acceleration going uphill

the check engine light is on and you still are running it without checking or having the fault codes read
the light is to stop you from driving it before it gets serious
read the codes and hope that you haven't damaged it
