My car stalls immediately after start!

[dan]

Hi guys,
I have a Honda civic 1.7L vtec (2004) car,My car stalls immediately after start!(most of the time), but after starting it again I can run the car without any problem,recently I repainted my car,i noticed painter
hd removed some of the earth cables (there were few earth cables ),is tat something to do with that?coz all stated after repainting my car.:(
Note,-I’m running with a faulty o2 sensor,(I’ve been running like that for about 8-9 months now).

also my gears are not engaging properly (Automatic transmission)(cvt i think)
sometimes gear indicator doesn’t show any status ( whether itz R, D ,N or d1,d2) ,but can move in to a position after moving the gear shaft a little.why is that? 🙁

Kp

Not having the electronic components properly grounded can cause unusual and wierd effects. Also, before you truly can do a diagosis, fix all the known bad things I.e. o2 sensor…it may not have a direct effect, but will eliminate some other diagnosing…

Also, is your gear indicator display digital and not working…that can be a ground issue as well….

Keep us posted…

Yes the painting and removing of grounds is definitely something you need to look into. A single loose ground connection can cause all kinds of problems. Maybe you could take your car back to the paint and have him look over all the grounds that were removed.

Grounds, yup, they can screw up tons of things.

Maybe just me, but mate, I would replace a known bad O2 sensor before I would spend money on paint.

That O2 could EASILY cost you the price of your paint job in extra fuel over the course of a year.

yes i will check that with my mechanic,no itz nothing to with the gear indicator, indicator is working ,some times i get in to a gear positions which belongs to no where. for a example if i change my gear to N to D some times it not gets in to D position,i can get to the gear posttion after wiggling the gear(stick) a bit.

Check your shift linkage at the trans. .. it may be loose or binding somewhere…

thank you very much,just now i got a call from my mechanic , he thinks its the gear switch ..I’m clueless,but he said that he gonna check the linkage as well…

First of all if the shifter range switch is worn or dirty (mostly from spilled coffee), the engine computer will have NO idea what gear the car is in and has no idea what the idle speed should be. This could cause the stalling problem you are experiencing.

If the fuel trims are off while running it can have an effect on the fuel mixture on the next start.

You will likely save money on fuel with a new sensor if it is in fact bad.

is there a fuse for a o2(secondary) sensor? 😳 if sp pls help me to locate that.. i have attached the fuse layout of mine

I don’t believe I have ever seen a car with a fuse for the O2 sensor. The sensor gets power from the ECM, which is protected by it’s own fuse, no real need for a separate fuse for the sensors.

The o2 sensor should have a o2 sensor heater circuit fuse.

[Tom]

That made me take another look at my wiring diagram for my car, and I don’t see any indication of a separate fuse for the heated O2. Looks to me like both the sensor side, and the heater side get their power directly from the ECM, and I only see one fuse for the ECM.

Is this perhaps something that is handled differently on different cars? I don’t recall ever seeing a fuse specifically labeled for the O2, but then I’ve only dealt with a hand full of fuel injected cars.

[college man]

The fuse can be labeled as fuel management or something like
that.It could also have other things on that circuit.
