I had to junk my 1999 Savana 1500. The frame was so rusted it was dangerous. So I'm looking for a 'new' one.
Found one for $1500 (same year and model of my old one). Guessing it has a 5.7 inside, why would it not accelerate past 30mph?
1999 GMC Savana 1500, 5.7, 140,000
Don't have much info on it now. Will inspect it this weekend. Anything I should particularly look at? After owning one for 10+ and doing a lot of repair, I do "know" my way around this beast.
Any ideas?
Thank you.
PS If the link doesn't make it thru, here's the craigslist text:
condition: fair
fuel: gas
odometer: 138000
paint color: green
title status: clean
transmission: automatic
type: van
Won’t accelerate passed 30mph,missing inside door panel. Passenger mirror housing broken. Backseat won’t fold up Van is in fair condition four used new tires. Clean Title.

There are few things that can cause symptoms like that.
I'm assuming you are getting the same RPM limitations in Park and Neutral.
Plugged Catalytic Converter
Low fuel pressure
jumped timing (also hard starting)
Transmission problems
