I have a stock 96 civic auto as my daily driver for the last fee months it has developed a reason bogging concern. When cruising bellow 3000 rpm it will start to bog like it's running outa fuel. If u boot it it clears up and all Is fine. Fuel pressure is good new filter plugs cap rotor wires new. It's so random it will be fine for days the then come back. Just wondering if anyone else has experienced this. Gonna check o2s and map Tomorow

So Frusterating to diag because it's so random

 

Almost a 100 km round trip today to work and back didn't do it once. I forgot to mention no codes

 

I'm leaning towards random map issue

 

It wont be the map sensor unless it throws a code. Check for any and all stored codes first.

 

There are no codes I heck it everyday this isn't my first rodeo

 

Replace the upstream oxygen sensor with a Denso.

 

Common problem ?

 

The oxygen sensor only is used at idle up to light throttle. Its possible your oxygen sensor is fouled.

Not saying its going to fix your issues but its definitely possible.

I would check for an exhaust leak using seafoam anywhere from the exhaust manifold to the oxygen sensor first.

 

No leaks Thanks for the tips

 

had a similar issue a few months ago, was barely noticeable and got worse over a couple months. Had to replace an intake valve with a nice chunk burned out of it. Compression test and then go from there. I found out really quick due to zero compression in cylinder 3. Good luck!

 

Thanks but a burt intake valve would create a noticeable miss. This is not like that completely random

 

Had the same problem. But now it also stalls. The car is practically worthless.

My suspicions: Faulty ignition switch wiring, or fuel delivery issue. (pump/filter/injectors) etc.

Let me know if you solve this!

 

Tighten/clean G101, ground on thermostat housing.

 

I replaced the map sensor on sat with one from the wrecker has been good ever since I will update in a few days. I commute almost 100 k a day so if it's not fixed it will happen soon. But is very Frusterating as it is so random

 

i worked on a civic with same issue. it had egr though cleaned out all ports and ran fine after that

 

96 ex auto doesn't have egr does it ?

 

Map sensor has seemed to fix the issue fyi

 

Been running great all week

Shoulda gone with my gut from the get go and replace the map

Oh well go a good used one from the wreaker for 10 bucks
