hi all

 

I have 300zx tt 93 , recently i faced an issue with mine

 

1_ sometimes while driving and shifting smoothly the engine will stop running but if am shifting fastly it won't stop running i believe cause the rpm still more than 1200 rpm and its happens also while stopping for traffic lights and similar situations.

 

2_ i have speed cut after 2500 rpm once pushing on gas fastly , but if am pushing slowly it will go more than 2500 rpm but slow.

 

any body knows what the issue am facing ??

 

note : i noticed that i don't have fuel filter in my car.

 

Thank you all in advance

Welcome to the forum faisalsb. You say you have no fuel filter fitted so I would fix that first as your engine is taking in all the grime from the petrol tank.

 

As Gary said, sort your fuel filter out.

 

Is the cutting out after being on boost? I had a massive air leak that was causing mine to do that. It could also be the aicv at the back of the plunum not working as it should catch the Revs before they drop too low really.

 

The acceleration issue, I'm not sure if this could have some thing to do with the lack of fuel filter, but it could be a wet MAF
