Started the car this morn and the gauge is stuck at +7,any ideas? Car is driving perfect..

gauge or sender unit.. have a look drivers side firewall near break master cylinder, there will be a vac line from plenum balance bar to a small sender unit.

check electrical connectors to it, try unplugging it and see it it makes a difference.

 

there is most likely a guide on testing it in the FSM.

page 46.. for sender unit test..

Thanks for the reply medallion man,it has to be electrical, jus put the lights on there now and it's working perfect, turn off the lights and it sticks at +7 again, strange 1

This car is jinxed,the lights are stayin on now when there switched off,parking light stayin on on passenger side and full light stayin on drivers side. I had to jump start it with jump leads few days ago, hope I didn't damage the Ecu?? Also the abs light is on since I bought the car and the hicas light came on for a while one day as wel then went off.. The wiring harness looks mint condition

typical jap electrics

Could have a dodgy fuse box next to the pedals.

Sound like it could have got wet and is now causing some electrical gremlins.
