Some help pls.
The service light on my cab along with the seatbelt light on the instrament cluster keeps going on.Does so for about 2-3 minutes at a time then goes off.Also the iddle seems to be jumpy, after driving for more than 1/2 hr, she seems to want to idle at 2000RPM, sometimes the idle jumps, between 1000rpm and 2500rpm, what could be the prob?Ive had the car serviced at 130 000km, and its now at 136 000km?
