My b16 Slighty Hesistation

[94EJ1OwnS]

Okay , my car is has slight hesistation at 2-3k rpm but it goes away when you kind of slam on the gas pedal or when you turn the car off and start it back up , idk whats the problem , dont know the history on what been change or whats old , only thing i know is their a recent oil change , recent sparkplug and wires , and oil filter . . .

could it be the o2 sensor , or map or tps or what. . .

Check engine?

my car seems like it wont let me past 2k -3k rpm , sometimes , idk whats the problem , just want to get it fix myself before i bring it to the shop .

Check injectors cuz my Ls had mismatch injectors & it did that

Check engine?

yupp , due to the secondary o2 sensor , its not plug in , cus it has a new exhaust system so neva got a chance to get the exhaust tap for that sensor

how can u tell if its mismatch ? ?

must be ur tps and the other connector (cant remember) in the throtle body have a solid connection in the connectors. i had the same prob, i coudnt go past 3K or so and my connector didnt give it a solid connection making it run rich

[94EJ1OwnS]

well dont assume that its only ur o2 sensor dat is throwing a code.. did u check your codes?? wat ecu u runnin... and if all the injectors are stock, they are the same the only thing is that the ecu changes tha amount of fuel being pumped out...

i think it could be your ecu..chek that out i hadd saim thing nd it turned out to be the ecu i was useing...

nah its a 02 sensor , check 3 times , one by my mechanic , and at autozone , and a another mechanic shop , throwin secondary 02 sensor , and when i start my car , cel is off and 5 seconds later is on , so deff my 02 sensor , and the motor has no leaks or knocks or funny noise , and doesnt blow out smoke , so idk maybe the injectors are diff , or maybe the i.m or t.b and sensor are bad , and im running a p30a02 b16 obd2a ecu

i dnt think its my ecu i try a gsr ecu and a single cam ecu , still doinq the same , its either the tps sensor or map or suttin do with the tb or i.m or injectors
