ECU issue? 2004 V70 V70-XC70 2004

posted by  someone claiming to be ibs740 on  Mon May 11 16:05 CST 2020 [RELATED]

Hi All,

Yesterday my 2004 V70, 2.4 NA, 5sp stalled in traffic. It would start then die, 10X starts and died each time so it came home on a hook.
I found a problem in the cable connecting the MAF. Voltage was as speced but the resistance between pins 4-5 was 1.8 M ohm. I found the ECU locking bars were not fully engaged. I tightened them and the car fired right up and drove normally except the idle was low 600 vs 750.

Starting cold the engine has the normal high idle then it drops.

Today I started the car backed out of the driveway and it stalled. When the throttle was let off the engine revs drop and the car stalls.

No codes so I'm guessing it's the ECU.

Thoughts?
