i currently have a
1999 Ls JDM b18c swap Integra
stock p28
b18c bottom end
cp pistons
manley rods
b16 head
Supertech valves valves springs retainers

problem i am having is...

after the car warms up to normal opperateing temp. , when i hit the gas at about 50% throttle its like im at 0% throttle.

but if i got 75%+ on the throttle the car will go.

its like the motor isnt getting fuel or my throttle body doesnt open up unless i press the gas hard

and after its warm the car will try and idle at like 500-600rpms and normal is 800

but if i turn the car off and back on it will run fine for about 5 min. then continue to do the same thing

i got a new ecu
new engine wiring harness
had my TPS sensor recalibrated

do i need a new TPS

i have a feeling its a senor i just cant figure out which one...

any help would be greatly appreciated

i will try and get a video posted ASAP

my shop does not no the problem and i need to get motor tuned and i dont want to put it on the dyno while its doing this

Thanks.

Nick

 

help any1?

 

Sorry if it doesnt answer your question but how do you recalibrate the TPS ?

 

Is it a 5 speed ? if so every think the clutch went?

If the TPS has rivets on it, it never needs to be calibrated. It just needs to be replaced and then you have to calibrate it after that. You recalibrate it by back probing the TPS and reading the voltage at closed throttle with the ignition on. It should read near .5 volts, then you tighten the bolts, screws, or allens and test it at WOT and it should read near 4.5 volts. Of course if you have a SAFC or VAFC, you can just go to the sensor reading option and look at the voltage of the TPS there.

 

Are you throwing any CEL's?

Check the flow of your fuel filter....it may be clogged.

no codes at all ill check my fuel filter thanks man

open to any ideas

 

Try unplugging your TPS, you will throw a code 7 but if your car runs fine you know it's your TPS. I'm have a TPS problem and can't get it working so I have been riding around with my TPS unplugged and the ECU is using the signals from the MAP sensor to calculate air flow and load.

Buy a used TPS. Most Honda TPSs are interchangeable.
