Greetings, everyone!
The Volvo 244, an 84-family car, starts fine; however, while driving, it suddenly slows down and seems to stall before picking up speed again. This behavior occurs randomly during driving. Recently, I installed a new in-tank, stronger fuel pump (AEM-5-1000 High Flow) to address the issue, but it hasn't resolved it completely. Have cleaned throttle body, spark plugs, and air idler valve.
I would highly appreciate any tips or insights based on your experiences to help me diagnose and fix the problem. Thank you in advance!
