Hello Guys!

My car have a big problem.
The engine sometimes,in different rmp,with different accerlation,halting.

This is a heavy problem. When i accerlate with the car, the halting size is horrible..2-3seccond.I think that the engine shut down for a while,and have got a huge amount of engine brake, and after that everything alright.

So i dont know what to do.

Star diag dont show anything like that.transsmission communicate faliure,but after delete dont come up again,just after a while..(1000km)


My AC pump is dead?Or do i have to change AC pump filter?or some leak in the vacuum system?deadlock transmitter?

i changed the new AIR MASS sensor, it doesent solve the problem.
I cleaned the thortle body,doesent help.


Does anybody make with star diag, engine reset?


Thank for helpin

 

Check your TCU (egs) maybe have oil inside

thanx Fabio Daniel!

It may solve the problem? What does it mean EGS? TCU=transmission control unit.

EGR valve cleaning or replacing could be helpful?

 

Can anybody help me?

 

No one can really diagnose this from afar, but can only offer things to check. Normally having a major shutdown like you describe would throw misfire codes. The only thing you have gotten, on a recurring basis, is a transmission communication error, so check that out. One known problem is for ATF to seep up the cable to the TCU (under the hood, passenger side, under a cover), so check that for oil.
Then get the transmission read to see if had any stored codes. The tranny has its own codes.
And no, your EGR will have nothing to do with this.

 

Thanks!

Maybe air in fuel tube can make this?

 

You didn't receive any mixture-related codes to be expected with a fuel starvation scenario.

 

I don't understand you very well. Did you have the car hooked up to a Star diagnostic computer? It sounds like you did and it gave you a transmission communication code or codes. A very common problem area that might explain your symptoms is fluid in the transmission control unit and that has been suggested several times. That is a very easy thing to check yourself so have you done that yet?

 

Hi again!

Still a have got the problem, but now the Star diagnostic show up B1204
it means, Fuel Sender circuit short to ground.


Maybe at the fuel pump,there is a unfix cable, or do i have to replace the AC.


The car sometimes when i accerlate,it feels like the engine wont got any fuel for a second, and after it is ok.
Do i have to replace the AC, or just fix the cable connection somewhere.?

Thx
