Fuel
 

ok so i fot the 92 civic hb for like 500 dollers and ne ways there is something wrong with the car. The car is fine for the first 3 min. Then the car dosnt resond with the gas. i have to floor it to get it to go it will slow down and one i floor it it like gets a kick in the but .... if ne one has a idea it would be great

any check engine lights ?

id say try changing the fuel filter and running a couple bottles of system cleaner over the next 2 fillups and see if that has any change on it

rereading it sounds to me like the tps might be gone with the wind

none are on

i say it's the O2 sensor. Mine fouled out when my car was boosted, and when you start it it'd be fine, then it would warm up and start to bog out, and jump and misfire. My car was running so rich (because it was already rich and then the ECU adds more fuel when it doesn't know the A/F ratio) that i had misfires on all four cylinders and my check engine light even started to blink! Then i changed the sensor and it fixed it.

But also check other things too like your plugs, see how they look and what the gap is.

Try unplugging the o2 sensor...

My car boggs out HARD then when you floor it it goes full blast... then once you let up on the gas again it boggs... you floor it it goes full blast... etc etc.

I re-wired my o2 sensor REALLY POORLY when I did my header... for me it's just a matter of soldering the connections and covering it well...

you MAY need a new O2 if the car runs fine with it unplugged... that or you could just run with it unplugged.

If it's not that then it could be a lot of things... TPS, Fuel Pump, Bad gas, Bad Fuel Filter, distributer... and on and on and on.

First thing you should do is check for error codes. Could save you some time.

Your car is probabaly pissed off at your horrible typing and won't run properly till you fix it.
