Do you have a scanner? If not you can go to autozone and have codes read, To properly diagnose this we really need a scanner, Usually unplugging the maf and it runs better is an indication the maf is bad because when you unplug it the computer runs off a fixed value and since that is the only thing you unplug the rational is that well that's the problem. But you are saying you can unplug either one one at a time and the problem goes away?

I do not have a scanner, and dont think I am suppose to drive the van if the check engine ends up flashing. I dont really have a rational, as I dont have experience with this van, and the engine is hard to get to. But yes If I unplug the tps, I get the solid check engine, limp mode first gear, but not flashing. If I unplug the maf same but dont know if it goes to limp as havent tried. It was find last night just acted up this morning.

Okay without a scanner any work or diagnosis we done would be firing the parts cannon. We need to know what the codes are and also the data, and you are correct do not drive if ligh is flashing. I am not sure how I can help you hear are you wanting to diagnose this yourself

Customer: replied 1 year ago.
i tried and it will allow me to drive it, though rough, with the maf off, so I can get the codes pulled. Would you like me to send the codes to you in a bit when we retrieve them?
Expert:  Reggie Whiddon replied 1 year ago.

Yes please when you get there hook everything back up, have them scan it record the codes have him clear them see if any reset, and if you can give me the short term fuel trims at idle

Customer: replied 1 year ago.
They said they couldn't give fuel trims. But they cleared the codes, ran the engine, light started flashing and got code 102 maf 122 tps and 300 random misfire
Customer: replied 1 year ago.
correction. those were the codes before clearing them. . After clearing the only code to show up was 300 random misfire
Expert:  Reggie Whiddon replied 1 year ago.

Okay lets assume the code from the maf and tps are were you disconnected them, and after clearing you had a po300. Does your engine have a flat distributor cap? you are in the year range were they changed.

Customer: replied 1 year ago.
from what i can tell it is flat, 4 from one side 4 on the other
Expert:  Reggie Whiddon replied 1 year ago.

Okay, replace it and the rotor. That is the worst thing chevrolet ever done. I am willing to bet it is causing some if not all of your problem

Expert:  Reggie Whiddon replied 1 year ago.

get a good one, I like to use AC Delco, what happens is it crossfires inside and can cause all sorts of problems. It is easy to replace and I will bet you a box of doughnuts your good after that

Customer: replied 1 year ago.
I am hoping I will be able to get you a box of donuts. I will get the distributor cap replaced tomorrow, need some Torq heads. However does it change anything if the van is an 2002?
Expert:  Reggie Whiddon replied 1 year ago.

As long as you have the flat cap no, The vans were the last to receive the engine change. The ironic thing here is the next series of engines are arguably the most dependable ever made by man on this planet. But starting in 07 some of the worst ever. no sir put that cap and rotor on, and I like the variety box.

Hi Reggie. Your diagnosis was right on. How does just answer work, what do I do to give you kudos! And is there an address I can send a gift card for a Doughnut shop so I can buy your variety pack? Hell you got me back to work in less then a day, thanks to you
Expert:  Reggie Whiddon replied 1 year ago.
