Oke so I have a 1995 honda civic EX with a swapped turbo B16A engine.

Now I just did the swap and the car idles, revs and boosts fine, but when I'm driving and i press the clutch in to change gears the car almost dies, the rpms drop below idle and when i reach a stop light that i have to press the clutch in and shift to 1 the car dies if i don't give it a little gas.

When i got home I noticed i had a CEL on and it was code 7 Throttle position Sensor, I checked the voltages with a multimeter and it read 0.1 while closed and 2.2 at WOT so I figured that was the problem. Adjusted the sensor to 0.5 closed and 4.5 WOT and all the CEL went away, the car idle better know

I took went around the block a couple of times and it was fine but as i was returning home it started to turn off again as soon as I press the clutch when i was stopping (No CEL this time) I checked the voltages on the TPS again and they where 0.8 closed and 3.8 WOT the screws on the TPS are solid and tight so I don't see how it could've moved. Can the TPS cause the car to die when i press the clutch?

This only happens when driving, if i start the car in neutral it idles a little rough but everything else is fine and i press in the clutch at it still runs fine in neutral.

Can this be a bad TPS?

 

So...when the trans is in gear and you hit the clutch, it dies?

There's most likely either something wrong with the clutch or something wrong with the clutch hydraulic system.

 

What???

 

Close .46 -.47
WOT 4.5
What EMS are you running??

 

His car stays on while in neutral and stopped.

His car dies when it's in gear and stopped (clutch pedal pushed in).

The clutch may not be disengaging fully.

 

The master clutch cylinder has been acting up today, the pedal will become loose and the clutch will not engage (I have to pump it a couple of times before i can feel the clutch engaging). I'll change the master cylinder and come back to let you know if it works.

 

Pretty much yeah.

 

it is possible that the tps sensor is bad due to the fact that the voltage readings changed after a simple test drive. you should reset the tps to the correct position and before driving open and close it a few times and see if it changes then

 

if you have to pump the clutch to make it disengage...then that's very likely your issue.

You may have a leak...which caused you to become low on fluid.

Or your clutch is not adjusted properly.

 

Still trying to figure out how it's the TPS.

 

depending on how the car is dying out I mean if its coming to a stop and jerking then stalling out I would definitely say the clutch is not disengaging..
