Motor dies when given ANY throttle...

[cp[mike]]

i stopped over oneoff's house to try to get his car running after he did a few things, including a partial wire tuck.

the car starts and idles fine. fuel pressure is ~25-30 at idle (what is stock supposed to be?). no CELs at idle.

the moment you give it ANY gas, it instantly bogs out and stalls. and by any throttle, i mean even the SLIGHTEST bit will kill it.

if a vacuum line is disconnected (to let more air in without having to press the pedal) the idle raises like normal, and it still idles fine. so its not necessarily giving it more air that is the problem, its actually pressing on the pedal that causes it.

that led me to believe it would be TPS related. we did not adjust it, because its still the same exact place it was before. even with the TPS disconnected, it has the same symptoms, but of course just with a CEL.




what could cause this? its running on a "new" map on the chipped P06, is there something about a specific ECU tune that could cause this symptom?

can u try the old map on the car right now? see if it does the same things?

we never considered the ECU at the time, im already home and about to go to sleep... already suggested to larry to try a stock P14 see if it makes a difference...

what map and what program?

Does it have a wideband? Try burning a stock map onto it...

the car starts and idles fine. fuel pressure is ~25-30 at idle (what is stock supposed to be?). no CELs at idle.

this is a F22b dohc motor aka H23, correct? that fuel pressure especially for a turbo seems loow to me. i dunno

stock H23/F22 fuel pressure @ idle w/vacuum should be 28-35psi.

without vacuum it should be at 36-43psi.

try disconnecting the vacuum from the FPR and see what its at (within spec). try giving it some throttle with it disconected and see if that does any.


its just a thought. sounds like ecu/map issues.

i had this same problem, everytime i hit the throttle the car died!

i took the throttle body off to clean it and accidentally broke the tps. the car worked fine before i did this!

So I got a tps from the junkyard, tried setting it using somones advice on this website but i had no luck, finally i gave in bought a used tb, threw it on and viola it worked..

well i got the fuel psi specs from work today. well check it out tonite if i can. the ecu isnt throwing any codes at all. the only time it does so is when u unplugg a sensor. will keep everyone inform of the problem. it has to be something stupid. im running a p06 with a crome chipped h23 turbo map

[KeeleDesign]

well the tps makes no since to me,, if it's unplugged that means it don't work so no thats not your problem,, my tps was bad throwing a code and i drove for 2 days on it.. i grinded it unscrewed one from a civic up in the field and put it on with a used gasket,, and it works just fine,, my symtoms were just a slight miss before i changed it.
it does sound like when you press the gas you are getting way to much air and not near enough fuel....

there is a possiblity..wait what type of 02 sensor are you using?

[oneoffaccord]

stock o2 sensor. throwing no codes

help me!!!!!!!!!!!!!!!

try the distributor. my car does it wail i'm drivin it will drop in rpms then i down shift and it back fires or it will just drop from 3k rpm to 0 then cuts out. and i replaced every thing else that would make it do that.

[SMseagren83]

any updates?

[gloryaccordy]

any updates?

distributor change or ajust it

[Phempa]

this might sound too simple, but check the ground strap from the engine block to the chassis.

this is a very necessary grounding point that I have had issues with in the past.

good luck.

i'm having the same problem as well, but if i keep on the throttle it moves, just bogs before it goes

also if i give it some gas, but dont keep on it, it dies, guess i'll check my TPS even though i didnt touch it when i did my head gasket replacement
