OBD 2 Problem

[baz8328 0]

I have a 1995 vr6 on a M plate

I thought my car was obd1 cos of rectangular side repeaters etc. However it has a obd2 portnear the ash tray.

At the moment i am havin a few problems.

AS i start the car and put my foot to the floor its stalls and dies so i changed the the lamda and cleaned the maf and still the same .

I paid a guy to come round with a full version of vcds and he could not get my car to link up to laptop DOH

So i am at my wits end !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

My last resort is one of these

[baz8328 0]

sort of

its in the boot of the floor under a black cover. But can figure how it comes out !!

Also when the car revs a bit the car seems fine but at lower revs it stalls

Its doin me head in !!!!!!!!!

will the vcds not link into any of the controlers on the car ???????? don't think the other scanner will be any better as it works the same way as the vcds (mate has one)

baz under the black cover is like a big black circle thing that looks like a big barrel lid unscrew this and you can get to the sender and pump have you checked f/filter ,fpr/etc

Could it be the knock sensor ??

Anyone got a coil pack / maf sensor i could borrow to eliminate these problems

is my car a obd1 or 2 ??????????????????

[Pearsy47 1]

only way i would tell is if you had a coil pack or a dizzie and the thorttle bodys are different !! i tell you somthing sounds like what i had and it turned out to be the bracket holding the throttle cable was lose check that out ! hope this helps !

Hey,first of all sorry for my english.I also had this problem just today,and I think it's this bracket holding the throttle cable,because when I pulled out bracket and putted in again the car started runing just fine!

[F1VR6 0]

o,and mine is also '95,I thought also that's OBDI,cause of the rectangular repeaters,and OBDI throttle body;but there are 288mm discs,obdII port near ashtrey,and obdII ABS system,so anybody can tell if obdI orobdII?

i bought a cheap code reader on ebay made by AUTEL and it reads codes spot on !!

I have reset the codes and every time i get this one back !!

00513-003

kwp1281

Engine speed sensor(g28)

Static No signal

What is this ??

How much is one ??

Would this cause my problem ??

was the engine running at the time if not thats why

[baz8328 0]

The code reader specifies not to have engine on.

So I reset all codes and this code keeps coming back

[russj249 2]

The engine speed sensor fault will come up with most German cars if the engine is not running and yes you're correct that you do the test with the engine switched off. So you can discard that code.

As for the OBD1 or 2. The easiest way to find out is to take a look at the throttle body.

Mine is on a '95 and has bits from both cars, inc OBD2 16pin connector, but OBD1 engine, wide arch kit, but also has the coil pack NOT the dizzy so Pearsy's way of diagnosing only gives you a rough idea.

There's the link to the different throttle body's

[baz8328 0]

Mine sounds the same as yours with bits of both obd1 and obd2.

What should I check next to rectify my problem ?

[russj249 2]

Well I'm not sure to be honest, if it's not bringing up any fault codes it's hard to say.

Maybe do a few tests, Disconnect you're MAF and see if it's any worse. If it's exactly the same it points to the MAF.

To be perfectly honest I'm not sure how good these handheld scanners are. We use a snap-on one at work and I have VAG-COM at home on another laptop.

It might not make any difference or pull any other codes out, but I'd maybe get it checked again for other codes.

Without looking it's hard to say what to do next to be honest. Electrical sensors should come up with a fault code but if no others are being pulled out it's difficult.

When you say it stalls how exactly does it stall??

Does it stall if you have foot on accelerator or not?

Will it rev free before it stalls or lumpy?

[baz8328 0]

It stalls as you put your foot down . But if you do it gently it and get it over a few thousand revs it run fine up and down but when u let it drop down to tick over and try to foot your foot down it stalls again . I have cleaned maf , checked ht and spark plugs and the coil packs looks in really good condition.

Please help

Fuel filter changed

New fuel put in

Sounds a little better but still hesitating when pedal pressed to floor.

Plugged in a code reader and it says the maf is at fault !

How much is a MAF ?

Anyone got one for sale ??

HELP

[Lukey. 381]

if you get one from TPS they will do an exchange of your old one for £58 i think. i just got one and am waiting for them to take off the exchange surcharge to find out end price

[baz8328 0]

could the maf be a cause of my problem ?its not beginning to do my head in !

[Lukey. 381]

mine is OBD2 and i was getting bogging, hesitating and hunting but it never stalled. but mine is def OBD2 so has the electronically controlled idle control, i dont know if it would make such a difference to the OBD1 which i think is vac controlled? i dont know if this is the case im just thinking out loud see if it helps?

[baz8328 0]

could one of the vac pipes be blocked ??
