engine gives out when floored

Hey guys i'm new on here. i have a 94 teg with a b18b1 w/47K, and when i get on the throttle hard and floor it my engine just dies out and comes back at about 3000rpm in whatever gear i was in when i floored it. but if i go gradually up i can go to whatever rpm i want. so if any one can help me out here i would greatly appreciate it thanks

Welcome to AF

Wow only 47k on a 94!
Ok to start what kind of maintenance have you done to the car? And what kind of mods do you have on the car?

i'll start by saying the obvious... don't floor it? :wtf:

Sorry but that makes no sense.

Auto or manual?

Sorry but that makes no sense.

HAHAHA. ahhh. thats funnny

try changing your spark plug wires. and while you're at it do the rest of the tune up.

ok its a 5 speed, with i/h/e, stage 3 clutch, short shifter, msd dist. cap, accel wires, msd blaster coil, greddy evo2 exhaust, and thats about all thats done to the engine.........so basically i can be driving along and if i decide to put it to the floor, right when it hits the floor it gives out and always comes back on a 3000rpms (if i am above 3000 which i always have been when i floored it)no matter what. everytime, so basically my ? is....is that bad and what could it be. but if i gradually push the pedal in then its fine as long as i dont go ALL the way to the floor i can rev as high as i need to or untill redline.

maybe bad fuel pump? that is a weird ass problem...

Yea I am coming up with nothing. Sorry but I can't think of anything at the moment. I will ask around on a local board and see if they might have any thoughts.

sounds like a fuel issue to me, maybe fuel filter, fuel pump.

Yes but the fuel demand would be greater at a higher rpm. That is why i doubt it is that, but I could be wrong. Just thinking out loud.

try resetting the ecu...might be some kind of problem there. or even the throttle body. maybe something is jammed up there.

I would really try the plug wires. When I bought my integra every time I tries to accelerate hard it would stumble and not accelerate. If i took it up gradually it had no problem, but when i floored it it would practically die. and it never had problems below 3000 if i floored it below that it would have no problem till 3000 then it would start to stumble. If I floored it higher than 3000 it would stumble and depending on the load I was putting on it almost die and it would pick back up around 3-4000 rpm.


Anyway I replaced my wires and it ran like a champ.

Hmmm, that sounds like the exact problem and solution. Try changing the wires

and if that doesn't solve the problem, maybe go over everything installed and see if everything is properly connected,

was this a sudden thing or did it happen after an upgrade?

alright i'll try that(wires) and the guy i bought it from said he got the ecu worked on or smt??? and it redlines at like 7600 now when it stock redlined at like 67 or 6800 but he has had some work on the ecu if that helps but i'll try the wires and check the fuel filter and pump thanks alot guys and when i do change the wires what do u suggest i get.....

this happened about a week or 2 after i bought the car when my friend was driving and he floored it and it started doing it

One of my friends had the same problem about a week ago with his civic. about 6k the motor would just shut down basically. I told him it was a fuel problem and he should check to see the fuel filter was clogged up. And sure enough it was, we ended up putting a new fuel filter in and the problem went away. However after it was fixed, when idling his car would idle up and down sounded like he was pumping the gas a tad, but actually wasnt. Donno what thats about, but im sure well figure it out. but anyways try changing the fuel filter might be clogged.

Excellent advise :bigthumb:

Your friends idle issue is more than likely the IACV you can do a search here in the Integra forum and you will find lots of information on it.

Haha yea ive seen about 20 idle threads
thanks bro

ok so i changed my fuel filter and it didnt do ne thing and my plug wires should be coming in within a couple days so i'll keep you guys posted on what happens

so we figured out what it was.......it was a bad throttle position sensor but its all good now thanks for al your help
