my compression test results, after the car warm up,open throttle and disable ignition/fuel pump and i got this

cyl test #1 210 #2 210 #3 210 #4 210,

this engine is a 1996 ka24de and i slam it into my 92 hatch

according to the manual the engines psi should be at 179? why is my engines 30 psi higher,


this is what the car has, s14 fuel rail, s14 tsp rewired, s14 coolant sensor rewired , s14 intake with rerouted vacuum lines /canceling swirl control and pulse air injection. two injectors are leaking, i get sluggish accel after 4000rpm, i might take pictures and a video for you guys to see.

more info that might help, new wires, dis rotor and cap, spark plugs gap at .44, fuel 91, new air filter, fuel filter has 60k mile on it 300zx fuel filter, also my o2 sensor has around 50k milies, i replaced it new,

if anyone has a 1996 obdII ka24de can i get a picture of your coolant sensor wiring from left to right, i wanan see if i wire my car right, and tps.

now my questions are,
why does the car have higher compression? and poor accelaration.


thanks for your help :D

your compression readings are higher than normal due to carbon build up in the cylinders. I dont know how much build up there is but according to the compression readings there's a lot there. Unless...that is.. that you have an unknown built engine with compression say...11 or 12:1. leak injectors can cause carbon build up. check your comp gauge. what were the first readings of all cylinders?
