Over the past 2 weeks on a cold start on my 2002 saab 93 started rough 3 times so far. It cranks fine, then it sounds like its running on 1 cylinder. I don't let it attempt to run I'll shut it off within a second as i can tell its running wrong, so i shut it off immediately then every time its restarted normal and then drives normal. I have no CEL related to it.
It could be a myriad of things of course but i was just thinking of a general tune up. Fuel filter spark plugs clean MAF and oil change etc. Almost seems like its a fuel issue.
I can trouble shoot the fuel pressure off the fuel rail with the Schrader type valve correct?
Fuel pump was replaced 2 years ago with pro parts sweden so its very very possible its on its way out.
