Hi, new to Forum and finding Jug to be a saint!! Just purchased a Marea 100 1.6 sx Weekend 2000 (W). Almost instantly became hesitant, lack of power, flat spots etc (no injector light). Stopped 10 miles later, after returning to car it ran like a dream for next 30 miles home. Left standing for approx 30 mins, started car and injector light appeared on dash. Although slightly lumpy, car seems to idle on all 4 cylinders and revs with no misfire. Test drove for 10 miles, light disappeared, back to normal for couple of miles then returned to previous state. Have now filled with quarter tank super unleaded and two bottles of Redex, used for 20 miles and made little or no difference. Removed battery earth for 2 hours then drove for 10 miles, injector light stayed off but still running as before. Problem seems to arise when car is getting hotter. Have multimeter. Can anyone help me please??
hi
sorry for the late reply, i dont check the marea section very often.
best thing to do first is check the resistance of all injectors using the multimeter on the injector wiring harness. the wiring harness has a connector at the right hand side fo the fuel rail. use that connector to do your tests. you want at least 13ohms on each injector. if you search the bravo/a section you'll find more detailed instructions explaining how to diagnose and replace injectors.
second choice would be lambda sensor.
since you do not know the history of the car it could simply be bad HT leads or spark plugs, so a full service is definately something to do asap.
