So for the last few months my car has had a small stutter from gear to gear, almost like it wasn't getting enough fuel or getting enough air and the check engine light has been on. I assumed the check engine light was on because of the aftermarket exhaust. Well today I was curious and took it to my local Chevrolet repair shop and had the car scanned with the Tech 2 Chevy scan tool. It came up with like six codes, one of which was a clutch pedal code??? Anyways, the others were for the egr system and the catalyst system. So the guy checked my fusebox, I had a small simple fuse burnt out. Fired up the Scan tool, deleted my codes, and it cleared all my egr codes and my car has no stutter at all anymore, gets better mileage, and idles smoother.

I've been saving hundreds of dollars because I thought this was going to be a thousand dollar fix and it turns out it was $31.80.

Crazy.

It's good to know though that there isn't a damn thing wrong with my cobalt!!

 

which fuse was it?

 

yeah my damn check engine lights been on too. Same problem feels kinda like the gas pedal is freaking out.

 

come on dude. list what fuse it was!!!!!!!

I had this when it was cold. Threw a code. Turned it off and on again and it was fine. Just tried not to take off soon as I turned the car on. It's been fine since but i will check my fuses

 

ya my car has been doin something like that...like a stutter in the shifting...especially since its been cold out too.

I havent gotten a CEL code either btw.

 

I've been having the same problem

 

$31 to fix a fuse??? was it one of the big ones or something? or was that for the scan too?? just wonderin

 

what fuse was it damit you cant go telling us your fixed problem with out telling us all of the fix!!!

 

tagging this post in case in case it is real

 

So what fuse was it, I've got this shifting stutter problem as well and it's driving me nuts!

 

i guess were all having this problem in the cold. It goes away once the car warms up. man this guy must love teasing us

 

well I know a few cars around me were having a problem with the relauys popping out from wheel hop.... thought they blew up their cars....

 

I'M SORRY GUYS I made this post and got offline and went to bed then woke up and went to work. I'm going outside to grab my fuse box and take a pic of which one it was haha it'll be posted in like two minutes.

 

The fuse that was bad was the ecm/trans fuse, it's a 15A fuse. I was saving hundreds to fix this problem and a 15A fuse, which the cars come with extra, was the only problem.

Keep in mind ALL these codes were cleared when he put a good fuse in.

PO833 - Clutch Pedal Switch Circuit
PO443 - EVAP
PO141 - H02s B1 S2
PO135 - H03s B1 S1
PO102 - MAF Low Frequency
PO036 - H02s B1 S2

CHECK ENGINE LIGHT IS ON
CHECKED CODES, SEE ATTACHED PAPER, REPLACED ECM FUSE, CLEARED CODES, DID NOT RESET, ROAD TESTED CUSTOMER TO ADVISE

The 30 dollar charge was for a half hour of labor and use of the Tech 2 scanner but the guy was amazing helpful and advised me on a few other things. Replacing this fuse though did more then wonders for my car, instead of chirping second it'll roast the tires through about 55 and then spin going into third gear again like it did before!!!!!

I couldn't be happier.


Unfortunately though my check engine light came back on today after more then 24 hours of not being on but it's because my catalytic converter is emptied on the car. It still runs amazing so that fuse is definitely worth checking if you have a problem.

 

I have a feeling you'll have problems with the emissions people in a couple years with your current exhaust, lol.

 

Nah, I know a local shop that inspects and does performance modifications all the time and then chooses to overlook them come inspection. They've done ALL my exhaust work and they know me there, I'm good for life.

 

was the fuse actually broken like fried or you think that it was just a bad one?

 

cool if this happens to me, I know what to look for.

 

I've seen a lot of the Clutch Pedal Switches come in. Its a switch at the top of your cluctch pedal assembly and when you push in the clutch it pushes in this little plunger. It only sets a CEL if you change gears without the switch sensing clutch movement. Just make sure your pressing the clutch fully.

 

Or you could have gone to Autozone and had them scan it for free.

 

I've been to autozone a few times and done the scan there but I wanted the detailed scan that showed everything. The Tech 2 does a lot more of an in depth scan and takes readings to make sure the car is running right too, peace of mind is worth 30 bucks to me my friend.

 

was the fuse actually broken like fried or you think that it was just a bad one?

He never actually showed me the fuse he just walked over and said he replaced it with one of my spares, I would assume that it was totally fried.

 

the fuse is a emissions fuse under the hood it is a 10amp mini my check engine and tcs light were on and the car was banging into gear that fuse was blown i changed it and now the tcs and check engine light are off and no more banging

 

This was going on with me and i had no clue what to do...and was in the same boat as you with thinking i was gonna drop a boat load of money. THIS WORKED!!! THANK YOU X a TRILLION!!!

 

Holy 5 year old thread revival batman !
