Okay so I start the car it idles fine, I can rev the motor and it revs fine with the clutch depressed; As soon as I put it in first gear and let the clutch out and start accelerating the motor won't go past a certain rpm (car bucks) and will pause (almost like a restricted performance situation/limp mode) the motor will then buck to higher rpms. After this initial problem the car runs fine but this happens every time I start the car. I did get the code P0132 high voltage O2 sensor bank 1 sensor 1 after a while. I'm not sure if this is a false code the O2 sensor is very new. . . Any other suggestions on what this could be, before I buy yet another O2 sensor

 

Check your oil level and fuel level.

 

Both are good; like I said I can start the car and rev it fine to redline if I wanted. It's when I start going when the problem occurs.

 

I've got the same problem. It usually occurs when I've just started the car and go for a drive. Then, it does its engine bog thing, regardless of the pedal position. After about 3-5 seconds of the nonsense, it drives normally. I've been dealing with it for the past 2.5 yrs now and could never figure it out???

 

At what rpm does it start acting up?

 

On average about 2500-3000 rpm. Sometimes higher sometimes lower.

 

Coils, plugs, clogged cat

 

This. Most likely one of the first two.

 

Cat is new, planned on changing the plugs soon anyway, and is there a way to trouble shoot the coils? So I don't have to replace all of them. . .

 

Did you change IM gasket or remove IM lately ?

 

What brand O2 sensor did you get?

 

to truoble shoot the coil pack .take it completly out hold the botom and top try moving it and if its moves or is soft then ciol is bad .but i dont think thats the prblm if it was it will misfire allthe time.

 

i waould tell you your CAT is definatly cloged . u can buy another 1 or gut it .ill say save some money and gut it but u need a vibrant O2 spacer to clear the cel and inspection . THIS IS FROM EXPIRIENCE

 

The IM was removed a while ago when I had to swap a new motor in. I'm finishing up porting an extra one I have now, to put on and I ordered all new gaskets.

The O2 sensor is a BOSCH.

 

You may have a air leak there.

 

These ECUs dont like Bosch primary O2 sensors.

Very possible that's what I was leaning toward or something with the throttle body. I doubt torque spec was followed it seems like its just a suggestion to some mechanics. . .

 

Is there a brand you suggest?

 

Oem. PM Paul though. When I replaced mine with a Bosch he said Ill most likely have problems with it, but since Im running it on the secondary it shouldnt cause issues.

BTW, your rev cut-out is very similar to when my fuel pump and FPR went bad. Maybe take a look at that as well. I didnt get any CELs when that happened however.

 

Paul?

Get a Denso or NGK sensor for the primary, I have seen several Bosch sensors cause all kinds of running problems when used as primaries, the Bosch sensors just seem to update really slow and causes the ECU to overshoot trying to correct the AFR.

Also I would get you Fuel Pressure checked ASAP.....

 

I have a Denso sensor coming. . . hopefully it fixes the problem.

 

And fuel pressure???????

 

I think I figured out what was wrong. When I took the throttle body off to put my ported intake there was gasket maker plugging one of the veins to the top sensor. I also installed a new O2 sensor a Denso one and everything seems to be fine now.

 

So I had some misfire problems a day before my last post on this thread and was getting the code P1399 Random Misfire. I had just recently put my ported intake manifold on. . . so i took it off and it ended up being a vac/emissions line was unplugged from the intake runner (injector base flange). I re-installed the intake manifold and the car ran great I took it on an 800 mile trip no problems at all. Just driving back home from the gym today about a mile drive I get the same code. Could that plug have come back out of the injector base? It seems like if it ran great and no problems over that many miles what else could have gone wrong in such a short period of time?

 

So I took the IM off again today and triple checked everything and everything looks good. I ordered new plugs (NGK Laser Iridium Plugs). So when they come in I'm going to swap them out and see what happens. I'll keep posting for future reference.

 

I put some fuel injector cleaner in today with about half a tank of gas left and filled it up. The car seems to run smoother now. My initial problem was probably due to bad fuel and had nothing to do with the IM I think. When the car started misfiring again It was the day after I let it sit for about a day and a half. So my thinking is whatever was/is in the tank settled and got into the fuel system somewhere. . .

 

and that's why i only buy shell premium..

those no name gas stations . you never know how old or crappy that shit is.

just to save 1 or 2$ a tank isn't worth possibly screwing up the car.

 

Seafoam it, most gas is the same and the only way to tell the difference is to see it being processed yourself.

 

I pulled the plugs today and am doing my best to try to read them. The car is back to running rough again and miss firing. I'm going to install the new plugs when they come in. . . I have a feeling it won't fix the problem so after that the car will be going to the dealer to get the fuel pressure checked I have a feeling it might be way too clogged or the fuel pump is going bad (as suggested by civic and nva)

 

I installed the NGK's last night and the car seems to be running normally for now. I'm going to drive it for a few days and I'll post back.

 

I'm 90% sure the car is fixed now . . .no sputtering and it idles smooth now. So apparently one of the old plugs went bad or backed itself out just enough to miss fire. If it starts acting up again though its going straight to the dealer I don't want to blow the motor. The car actually scared me like it hasn't for a long time when the vtec and imrc kicked in

 

i throw new plugs in every 2 years.. i figure the mileage you preserve that u'd otherwise lose will offset the cost of the plugs anyways... and you prevent other hickups the car may incur as you've witnessed

 

I had that same accel loss issue with p0132, threw in 2 new Denso o2's off amazon and problem is gone. stressed me for a while but saved $$ so all good, hope this helps.

 

Yeah I solved the problem a while ago. It was the plugs. I also found that the car runs better with the Denso O2 sensor since that is the OEM sensor.
