What the @!$% ?
I have 91 e150 79000 that has been sitting.
-new plugs, cap rotor
-feul filter, air filter
-supposedly cleaned injectors
* This thing runs out decent when cold, but tends to be slugish in low rpm load situations.( like when it shifts to OD at low speeds)
It also feels like it has small power surges
- I checked the fuel pump pressure it's fine
Could it be the fuel pump is acting up?
I just don't know. If you have never driven one you would probably think it is just a slow vehicle, but I don't think anything should be this slow!!!!!
HELP PLEASE!!!!

Have you pulled engine codes yet? That might be a good place to start. Also, instead of the fuel pump I would consider the fuel pressure regulator a likely suspect. If that is shot, it could cause surging.
If you're running the A/C, it could cause "surging" as it kicks on and off, but probably not that noticeable. I know on my old car with a C4 at slow speeds, it would sometimes act like it couldn't figure out what gear it wanted to be in, so it would very noticeable kick in and out of gear between 2nd and 3rd. It could be that your torque converter isn't working quite right, and at slow speeds it's locking and unlocking?
Don't know, just throwing things out. Try running engine codes first. Then get to spending money.

Thanks! I actually did check the codes. I fixed all that stuff, which did make a huge difference. You hit it on the head about the van not knowing what gear it wants to be in. It dosent shift in and out, it just doesn't kick down when it should.

Hey Soupbone, have you tried adjusting the throttle valve linkage between the throttle body and the trans.? It's either a cable or linkage rod. It looks similar to the kickdown on other automatics. The AOD trans. relies heavily on this. If it's out of adjustment, it maight be causing the trans. to not upshift/downshift correctly. Be careful though! If you make it worse you may torch the trans. Consult a factory manual for the exact procedure. Mitchell manuals are good too. If you're not sure, have the local trans. shop do it. It shouldn't cost much. Good luck!
