99 V70 R rough idle after warm up and stalls Topic is solved

[kklepack]

After almost 10 months of dealing with this issue, I got a "free" OEM MAF and fuel pump relay from the local junk yard.

Fixed it a few days ago in 2 seconds.

Thanks for suggestion, but I did swap them as well and same symptoms.

Best of luck! You sure that relay was good too? Lol.

You also did this

. I also disconnected MAF sensor and no improvement. I

That doesn’t tell you anything about the MAFbut does tell you that there are other problems.

So, I found someones suggestion to :
a. disconnect battery
b. fully charge it
c. connect it back
d. put the key in ON position for 10 mins, but do not start the car

After doing so, car started fine with perfect idle for 30 min or so, then I took it for a short 1 mile drive around the area (as car has not been registered so did not want to take it for longer ride) and car ran fine.

Today, I went to start the can and it is back to rough Idle and staling. WTF!!!! I wonder if something needs to be reprogramed/software update?

I guess, I'm giving up for now. Next step is to get it registered (have to wait for State to open the registration facilities) and take it to Volvo shop around me.

If the battery is weak that will cause problems with ME7 (Your engine management software)

Whats the history on the battery? Use google to encode the date codes on it if you haven't replaced it or don't have history.

It is OEM Volvo battery and I can not find dates on it, I took the battery to O'Reilly auto and they said battery is good. I get 13.40 volts with voltmeter in battery posts.

Dont forget to put your zip into HELP IN YOUR AREA forum if you want to try get someone local to give a hand.

Whats the battery voltage with the car off after overnight?

[kklepack]

Just checked and battery shows 12.53 voltage.

So, couple days ago fuel pump was replaced as I did not have a pressure in fuel rail when the car was turned off. That did not fix the issue. Car still dies after few minutes of running, When I disconnect negative cable from battery for 10-15 min and reconnect it back car start fine and runs great for 15-30 min and then dies. I connected the VIDA and again no codes. I'm hitting the wall here. I think it is time to tow it to Volvo specialist shop in the are.
