Alright, so far I have replaced spark plugs and primary o2 sensor. Still have CEL and still have the symptoms

I had a feeling that the o2 sensor wouldn't cause this problem, but at the time it was the only code that came up.

Symptoms: From time to time (sometimes its frequent sometimes not) when I accelerate (esp slower acceleration) i will get a cut off gas (or so it feels like). I would keep a steady foot then it doesn't keep accelerating. So i keep pressing the gas pedal down. then suddenly it will jerk a bit because it'll start accelerating all of a sudden. so there's a lag. sometimes when this happens, i will let go of gas and gas it again and it doesn't create that lag.

and no its not a clutch related problem.



i THINK its ignition coils because a few people had this problem and said that's what fixed it, when I replaced spark plugs i didn't notice anything wrong. but whatever. what do you guys think?

 

My H23vtec does the same thing, but it's misfiring. I have a faulty distributor and a bad headgasket

 

I was going to post about about this sooner or later - but i also, as of late, have been noticing sort of the same thing --- only mines sort of a very slight, but very noticable hesitation...

Same symptoms, have only noticed it going slower speeds/lower RPMs - definately not clutch and definately not driver induced...

My throttle only cuts off for a split second then resumes as normal, doesnt stay "cut off" for longer than that.

Have noticed it 3 times in the last month and a half or so.

 

possible bad TPS?

 

mine has been doing the same...I did notice on mine that it occuring in the morning. I'll cruise at about 30mph and then there is a slight jerk, like a fuel cut off, and then resume...

 

That is actually normal. All 3 of my CL's have done it from time to time. Only at low rpm & only for a split 2nd. No hard reason for it. Some think it's a low voltage or sudden power drop problem to run something on the car.

 

damn now im not sure if its the ignition coils or not... i guess i'll have to buy a obd-II reader this weekend...

guessing on the fix is never ever fun for me or my wallet.

 

why not go to autozone where they let u use their obd2 reader for free in the parking lot?

 

they don't do that anymoreeee

 

all of them here do but that doesnt help you does it.


I have noticed the jerk too. I get it sometimes after starting the car and driving between 30-40mph at a constant throttle input. It is a drop in power for about .3 seconds and then everything is normal for the rest of the drive. It usually happens only within the first 5 miles of driving. I really noticed it after I put the blower on but it is not on now and it has done it without it. Jim

 

mine can last for 1-3 seconds... yeah.. depends if i step on it or let it go like explained in the first post....

 

If you have a AAMCO near by, they will read your CEL for free. I just saw a commercial on it. They also have AC check for free too. might as well since your down there anyways.

 

Mine does it. It got worse when I changed my o2 sensors. turned out I had a bad first sensor...

 

i just changed mine.. same shit.

 

Have you checked for vacume leaks?

 

not yet.


i ran the obd-II and it STILL says that I have p0132

I just changed it 2 weeks ago with a new one. bank 1 = the one on the cat correct? its acting exactly the same right after I changed it. There is no way that both can be bad. I only have 48k on the car.

 

Bank 1 is the first oxygen sensor. Maybe you got a DOA O2 sensor? What brand was the O2 sensor?

 

denso, i'm going to switch the other one as well... give me a few days. i'm PRETTY SURE i switched the wrong one =X

feel like such a

 

check for header cracks. Ive seen it happening to a few ppl due to a crack in the welds. When off the gas the leaks sucks in air and mess with the o2 reading. Just a precaution tho.

 

sorry to bring back an old thread, but did you ever figure out what the problem was?? I've been having the same symptoms for a couple weeks now, and finally the car threw a P0132 code... I have searched a couple threads with similar problems but as far as I know no one had any luck with a solution.

 

i believe its a bad o2 sensor but make sure you wont get Bosch just a Denso or other brand our ECU doesnt like Bosch sensors

 

This is what I got driving from NC to Boston last week and I am really happy with the mileage I got. This was also sitting on the interstate for an hour dead stop and driving around in Boston.
