Yeah, all fluids etc. then just run it hard (italian tune up). That'll get 'er running again
+1 on the Italian Tune-Up.
I also Seafoam every car I get a hold of. I know some say that is "useless," however, every single car this has been done to has a lighter-feeling throttle response after.. so, it is not "a waste" or "useless," whether it has never been done and there is smoke show that leaves two minutes after you do (you best be on the move from that smoke show, lol) or it has been done last weke and there isn't much of one due to not as much carbiin.. is why you sometimes DONT see smoke shows when you do this..
So, with that experience.. I find the brake booster, if it has one, let the engine bog down on Seafoam, then drop the empty Seafoam container and turn the key off as fast as I can since those few seconds waste the product.. Let it sit for anywhere from 15 minutes to an hour, start her up, and drive away. Smoke clears out in 10 minutes of hard revs, not necessarily hard driving.
Some cars don't have a brake booster line, so, no Seafoaming them.
Also, in addition to an italian Tune-Up, do a regular tune up.
ITUs get the engine good and hot.. and doing that really does it dome good. I lost all the coolant on my truck a few days ago. It runs better than ever now! And, no new leaks, thank God. I feel that would have killed a lesser vehicle. Mine just started right back up, all the way from hot enough to melt my coolant sensor to.. running very well.
