I have a B20vtec, when I accelerate almost half the time it jerks or is stagnate (barely pulls). Also jerks when shifting, it's hard to do a smooth shift.

Funds were low after the swap, so it's still running on old/used B20 spark wires and plugs. The distributor is from a 99 Si and rotor hasn't been changed. Still
running on the B20 injectors.

ECU is P73, fuel pump is 99 Si. Running on a stock exhaust system.

Please help. TIA.

 

has it ever thrown a cel? if so, check that, and either way, try replacing the fuel filter, they're like $10, so even if that ends up not being the problem, you didn't really waste any money

 

No, it doesn't throw a cel. I was hoping it'll be fuel delivery or spark management. But some said the B20 block and the vtec head throws off the oil pump sensor causing the jerkiness and I would need to switch to the P28 ecu. Any thoughts?

 

so by jerking do you mean it's missing? sounds like a spark problem to me.

 

What do you mean it's missing, what's missing?

like one cylinder isn't firing once in awhile, so it jerks.

do a tune-up. plugs, wires, rotor.
