6.5 diesel suburban question ???
Looking at a 97 turbo burb that I can buy for 1500 bucks truck needs a good cleaning and body is not rusty. Owner sent me a video of truck at idle. It seems to be in limp mode as it wont rev over 2000...

Did it have this problem beforehand - and that's why he replaced the PMD? Weird throttle response (or lack of) could definitely be the PMD. Could be a few things - none of them catastrophic, but can be somewhat of a pain to track down. I really don't know if this applies to all years, but I know at least some generations are "Drive By Wire" and have problems accellerating..
The 6.5 is no variant of the 5.7, and was a Detroit engine. :C
Is it a half-ton Burb? The half ton-equipped diesels were the "S" Code, while the HD's were "F's." A simple intake swap will an F will up your ponies a little, but don't ever expect a 6.5 to keep up with anyone else. Another great mod is a new fan clutch and a Dmax fan, then they will stay properly cooled. Then mount the PMD elsewhere. :) My favorite spot is in the hole on the front bumpers and mount a heatsink to it!
Properly maintained - they're descent engines that will give you pretty descent fuel mileage and reliability, but won't win any races or truck and tractor pulls. Though they got a bad wrap, if you know what to maintain on them and watch for - they're pretty reliable engines if you don't mind listening to the "clack clack clack clack.." :)
I'm by no means a guru on the 6.5, so some good ol' Googling would probably benefit... But I've worked on quite a few and have a lot of useless info bouncing around in my melon.
And though they share the same bore/stroke as the gas 350... The ol 5.7 diesel was a completely different engine. Same thing for the 4.3 "High Performance" diesel they made. All horrible engines... But I'd love to have one just because they're nearly extinct and just to play with it. LOL
