Why would a 1988 Nissan Pulsar run fine after being rebuilt but idle at about 1700 RPM and use twice as much gas?
It sounds as if you may have the timing adjusted wrong. The car should idle at 850 rpm I believe. If you adjust the idle the car should use less gas.
My Nissan Pulsar CJii rough idles especially after driving for a while at 100kmph and then stopping for traffic lights I have got it fine tuned twice and changed flowmeter but the problem reoccurs?
You may want to look at other options rather than the engine and fuel system. The most obvious problem would be if it is a manual would be the clutch is sticking a bit and may need to be replaced. If not the clutch assembly, check your master cylinder for jamming or leaks. This may cause the binding that is dragging your engine down when you idle.
Brian rebuilt his shelter twice, once because a porkupine got in, and left spines in his leg, so he tore it down, and built a sturdier, more secure shelter, to keep out animls. the second time, was because a tornado came, and everything got sucked into it, the shelter blew away, so he had to rebuils it again.
The Fifth Amentment protects people from being tried twice. For example (fake storie) there is a women who was accused of killing her husband. She didnt kill him but was put in jail for 10 years. She comes out of jail and finds her husband. She then kills him this time for real. She cant be tried for this same crime twice.
These were covered under a Nissan factory recall. Call the dealer, let them know about the recall for the crack shaft sensor, and it should be a free replacement. I have a 2002 Altima and actually had to get mine replaced twice...both at the dealer...both free of charge due to the recall on the part.
