what injectors

 

Stock h22 injectors

 

did u wire in the resistor box?

 

No i havent i wasnt sure if i needed to install it

 

yes, you need to install it. Do that and make sure all 4 injectors work.

 

if your injectors are peak n hold. which are obd1. tps too mayb

 

ok ill wire it up once i get time.. n ill let u know if it runs better thanks...

 

i just got a brand new TPS so i know that cant be it

 

if you're running stock h22 injectors. You NEED to run a resistor box.

 

thats wat everyone was saying so when i get time im going to install it..

 

if you dont mind me asking what kit did you use? qsd?

 

Dude sounds like one of your injectors are not working like it's misfiring check the spark coming out the spark plug wires with a screw driver. If it's not that than if the motor is obd1 jdm h22a it needs the resistor box if its a h22a4 than no resistor box needed but only if you have the 290cc injectors. If it's not that than check your injector plugs. It looks like it bogs out when you give it gas.

 

i have no kit...

 

i know its not the spark bec we already check that. n yea its a obd1 jdm h22a.. n thats what it does bogs when i give it gas...
