OK. Sorry if you've heard this before or responded to this issue, but I've spent many hours in this and other forums looking for related issues to no avail.
Issue: My non-turbo base V70 5 speed with 199k shows no codes, no cel, starts and runs terrific (besides the stalling). It starts right up but then after 1 mile or so will just stall. I wait 30 seconds and it will start back up. Then it stalls again. This goes on for several stalls/restarts before it will run normally. It will stall under exceleration or at a light. I have had it diagnosed (no - MAF, no EFI relay, no O2 sensor, no fuel pump, no computer module, no crank shaft sensor, and the throttle was cleaned.
Here is the kicker - this will continue for a week or so then the car will go several weeks with no stalling issues.
I would really hate to take it to dealer, since the car is not worth the $$ they would charge, however, some of these stalls get embarrassing - at traffic lights or going up hills.
