oil light and MFA

my oil light and buzzer come on intermitently when i'm in town traffic, as soon as i'm on the open road, it stops coming on…is this an oil pressure problem? also, the MFA comes on for the first ten minutes of driving and then goes nuts, off and then sometimes back on again…what's going on?

Could just be the oil pressure switch - think that's most common cause. It's cheap fix too so maybe your best bet?

thanks, i'll give it a go this afternoon, will be back for more help if it doesn't work….cheers
