94 k2500 no low end power and horrible fuel mileage

that is a powerful tool for OBD1 . not many have the availability to have this tool. It is a professional diagnostic tool....

There's a bunch of 'em on eBay, and they're not that expensive. Even a few MTGs.

There's also the non-Snap-On competition--OTC Genysis, and others. I've never worked with them...but they'd be similar to the MT/MTG from Snap-On in terms of capability.

Lots of options (and few excuses) for anyone who cares about fixing OBD-1 vehicles.

So after using my buddies scanner I found all sensors to be in proper working order. I did advance my base timing to about 4 deg and then unhooked the battery to reset the timing curve. The electronic timing advance is now working properly and the pickup does seem to have better throttle response. I also changed out the transmission filter and fluid, that didn't make a noticeable difference but needed done none the less. It seems to run and accelerate better now after doing that but still seems sluggish to me... Although I may be making an unfair comparison. I'm used to driving my other pickup which was a 97 7.3 Powerstroke diesel, with a hypermax turbo, 6 position custom tuned chip, 4" exhaust, and an ATS tranny... That thing would flat out move. So maybe it's just me and having unrealistic expectations of what this pickup is capable of I dono, but I do know everything seems to check out and be functioning properly.

put injector/intake valve cleaner in the gas use 93 octane fuel when you do this. could be detonation from the deposits .

I've sent lots of folks to this thread--specifically Posts 14 and 15--because it was easier than telling them anew about the capabilities of an OBD1 scan tool. But there's problems with the photos.

Edit: Figured out why the photos wouldn't show, and fixed 'em. Should be OK now.[/Edit]

Later Edit: Sometimes the photos show up for me, and sometimes they don't. Sometimes, SOME of the photos show up. I have no idea.[/Later Edit]
