Ok so about 3 days ago all of the sudden I was coasting in 4th and went to downshift to 2nd, all of the sudden the car died. Now its every single time i press the clutch in while under more than idle RPMs the car just stalls. Any suggestions? Cleaned IACV and raised the idle a little but still nothing.

 

ttt its a b16 btw

 

good luck getting a responce for any help on this site.but my civic did that and it was my intake manifold gasket went bad.

 

Have you checked for vacuum leaks?
Have you checked to see what you are loosing, fuel or spark?
What is the fuel pressure when engine stalls?
Have you checked wiring in the engine bay, all engine sensors, valve/solenoids plugged in?94

 

also did compression check and got 180,175,150,170 and getting some crankcase pressure...

 

150 is a little low compared to the others, [more then 10% off] but should not prevent engine from starting.
How about the other things I mentioned?94

 

everything else is goood :/ could it be pressure plate? ive herd that bad plates can do this?

sounds clutch related, either the clutch pedal is off or the sensor on the clutch pedal is damaged or the clutch its self is not engaging right and causing the motor to shut of almost like when you take off in first but dont give enough gas the motor will stall and shut off.

 

4th to second yea no thats reasonable makes sense weird how it caused a problem for ya

 

b16 have your integra trans or the b16 trans on it? Obd1-Obd2?

 

Have you set the base idle on the car?

 

its a b16 tranny, obd0 but i have obd1 conversion for the ecu and dizzy... idle was set when it got tuned, but i cranked the idle up a little more myself to try to keep it from stalling.. didnt work. It only shuts off say if im going 50 in 4th and i let off the gas and press the clutch in, car stalls. at an idle the car will not stall when i press the clutch in, however the idle will drop drastically.

 

Have you checked the TPS yet? 94

 

Yeah if your TPS sensor has just the slightest offset it will think the throttle is closed all the way and cut fuel for the injectors. You can slightly unscrew your TPS just enough to move it with a little effort from the fingers and you can fell when the spring inside moves with contact to the throttle body. I mean it's just about 1mm of movement or less.

 

do that with car running???

 

no motor should be off but the power should be on then you test the wires on the tps with a probe to see if its within range i think 4.5 ohmz at wot.

 

The TPS outputs volts, not ohms. It should smoothly transition in the 0.5 to 5 V range.

 

Map sensor

 

Yes.
