My V-6 4.3 Blazer suddenly started running rough and I wonder if its possibly a loose vacuum line or something more serious. Anyone have a suggestion? I lifted the hood and listened to unusual sounds..but nothing! It shakes and hesitates a little until I get over40 MPH!
What is proper way to check the trans fluid level on 94 Blazer (4.3)? I tried checking when the truck was cold in garage after sitting a few days and it was full past the hot line. However, I drove it today for about 5-10 minutes and checked it while engine running and it stopped at the cold level. What am I doing wrong?
