My bro's car keeps cutting at 3000 rpm and then he needs to shift but its once in while. What could be the problem ?

 

Its an EJ with a B16(Si) Swap.

 

not sure if it would cause that, but is he using the B16 ECU?
is it throwing a CEL?

 

Yes the CEL is on...we talk to the guy he bought it from he supposedly said he put the stock distributor with spark plug wires...could that be the cause?

 

so you're using the D-series distributor and wires on the B16 engine?
if so, that might be a problem

 

yeah thats right...cuz we called the guy today he was like just mess around with the distributor and we tried it and it didnt do it no more...so would it damage something if we leave it on?

 

i would get the B16 distributor just to be safe... especially since he said "just mess around with the distributor". Sounds like somethings wrong with it or it's like ghetto-rigged. I'm not sure if it would cause damage. But yea, I would get a new distributor just to be on the safe side, and so that it won't happen again.

 

Thanks trustdestruction, im going to buy it for my brother hopefully its just that.
