Wont run with the airflow meter pluged in , it also runs really lumpy on tick over but revs up fine. when you try and maintain a set speed it stutters. i need help its doing my fu##### head in :] 1996 318 is manual

different airflow meter calibrations,do you have the z32 airflow meter installed?

I had a similar problem. Nissan sr18di engine. car would run fine and randomly engine would cut off and only start after 20 minutes. Changed distributer
fine since

Please Check High pressure fuel pump. In my opinion your fuel pump connected to timing belt is giving away. When you increase rev on engine, the pressure increases as well. As a result, Injector spray pattern gets steady. But on revs below 900rpm it struggle to maintains required pressure. If everything in fuel injection system is working fine then the Worst case scenario is that the head pressure is leaking aka compression leakage.

Please check first basic things Air filter Fuel filter Injector Spark plug All above fine So you have replace oxygen sensor which located in first cat start Regard

try air mass meter

CHECK VACUM SYSTEM IF OK THEN THEN CHECK cpu AND ALSO FUEL PUMP SYSTEM

The battery could be slightly weak, making the computer go on the fritz, try a fresh battery!!!! The rev counters bounce often with a weak battery.

Leave feedback good or bad.

sounds to me like the tps is malfuctioning

hi had simular problem with my x300, when hot almost went into limp mode, replaced the cam shaft sensor, worked fine then went lumpy again the arm holding the sensor had cracked and was the cause of my porbem may be an idea to check here, hope this helped.. roy2k51

Hi there!

A few more things to check for you.-

A vacuum leak in any of the vacuum hoses will cause the ECU to make random guesses at what's going on.

Have you replaced plugs recently - or at all? This is probably the main cause - and certainly worth a try.

Fuel filter should be replaced at recommended intervals - about 3 years.

Clean your leads and HT gear really well with a degreasant. Any losses will be more noticable at tickover than high revs.

Lastly.........wear on cam lobes or timing belt.

Hope it's cheap for you!
Please spare a moment to rate as fixya! if any of this information proves useful. Thanks (I don't get paid for this)
