Hello all,
I own a 1998 Volvo v70 with about 219,000 miles, and recently when I signal left, I find that my car begins to sputter when I'm at higher speeds (45mph+). This makes it hard to merge, nor does it feel nice to drive, because the car will start jerking/sputtering instead of continuing to drive smoothly as it had been doing before. Does anyone have any ideas about what might be causing this? I saw a forum a little while ago that suggested fuel injectors but I haven't found it since.
Thank you!

 

Volvos are prone to weird behavior if they have any dirty grounds. I had a 740 that would outright die if I flashed the high beams. Cleaning up the grounds fixed it.

Go under the hood and wherever a ground point is, clean it up so it's shiny and tight. Just clean every one you can. See if the Fuel injectors have ground wires to the engine block; clean those. Then also make sure the ground wires for the lights- tail and forward -- are also clean and shiny. Hose them down with WD40 when they are all clean. Then let us know if the behavior changes.
