honda problem!!!!

[jdm-civic]

ok, the car is a 91 civic with a jdm b16 swap, pr3 ecu and everything is wired correctly and no c.e.l.'s. the problem is, while driving long distances at a steady rpm, the car will start losing power and bucking like it isnt getting fuel if i keerp the throttle in the same position but when i give it gas it will jump to regular power and feel normal untill i let off and return to a stable position, it will do it again. ive found a solution is while the car is still in gear turn it off then turn it back on and that will fix the problem for like another 20 mins but then it will start again untill i turn the key on and off again. what could the problem be?

anyone?

maybe the vtec solenoid. or maybe a dirty maf

maybe the vtec solenoid. or maybe a dirty maf

can't see a vtec solenoid causing that but weirder things have happened...i would look into a fuel issue.

[Starrfire]

maybe a really clogged fuel filter, could be a bad O2 maybe? You got any codes?

[Bacon]

He stated no CELs but I was thinking the same thing too. Fuel pump intermittently cutting out?

[RHD_Joe]

I've had somewhat of the same problem before. Try this disconect your O2 sensor and drive it and see if your problem continues..If the problem stops oviously replace the O2. Also are you running 2 O2 sensors or just one? If that doesn't make the problem stop then maybe you have a bad dizzy or fuel pump.

check your fuel filter, my aunt had the same problem with her accord and she replaced it and the problem went away

[jdm-civic]

yeah no check engine codes and it has a brand new fuel filter on it. i think i might try to disconnect the 02 and see if that changes anything, btw it has 2 o2 sensors and its a obd0 crx si harness

[jdm-civic]

and if it help, it had a knock sensor code last week but who ever swapped the motor didnt wire it into the ecu and i rewired it but the problem still happens

[Bacon]

is your CEL even working?

is your CEL even working?

MAFS are for Nissans, MAP sensors are for HONDA , so check ur MAP

is your CEL even working?

x2, if its any O2 sensors or anything im sure your CEL light would come up.

[jdm-civic]

yes my cel is working and functional

[james497]

check tha tps sensor i had tha same problem late throttle response

[jdm-civic]

hooked a dmm to it and it read fine.........

agreed, sounds like a fuel or maybe MAP problem. on my si the MAP sensor hole was covered by a home made gasket and it would stall going down the road and never throw a cel except for random O2 CEL's. also i thought most obd-0 cars only had the one o2 seonsor like a 1 wire or something. i don't know about the si harness.

[skeet]

sounds like a fuel pump problem to me. check wiring and all that good mess. also check the pcv valve and what not.

[NinjaHobo]

check your MAP.

[silverDA]

dam i had this same problem last week cause i put middle grade gas in my hot rod,when i put premium in it again problem solved.this is a tru story bro.

[jdm-civic]

it has no pcv, just a breather filter, and all i use is shell 93 octane.

[leroy12]

check your tps. mine did the same thing!
