Thanks for the link Steve.
No I do not have a code reader and AutoZone said it was to old to scan.
I'm thinking it is the TPS.
After I pass the dead spot I can rev the engine w/no problem, it is just when I let it drop to the dead spot that I have problems.

Hello, I had a check engine light go on. Brought it to 2 garages to get diagnosed, both said knock sesor issues. My van also runs very slow when stepping on the gas, till i reach 27 mph then the van bucks and is fine. Was also told it could be transmission. I can't afford to do either work on it and absolutely love my van and want to keep it since i have had major repairs over the years. any suggestions to what could be going on would be greatly apreciated. I do not want to get taken advantage of with me being a girl and all lol. thank you!!

Have the fluid/filter changed and the bands adjusted. If it has a vacuum module that could be bad as well.
I'm mainly a Ford truck/Jeep guy. But have worked on cars most of my life. Hard to diagnose over the internet but good suggestions.
#11 of 16 TPS Not the problem
Jan 02, 2012 (4:12 pm)
Well I changed out the TPS=No change.
I can feather the gas pedal and get it up to speed but the hesitation is still there.
When idling/engine cold or warm I can punch the throttle by hand and it will BOGG down and then start to speed up but it takes about 15 sec and that is not under load.
I was thinking Fuel Pressure Regulator but I can't keep throwing 50 bucks here or there.
Any other thoughts before I buy a FPRegulator.
P.S. Idles great and you can easy into the throttle and it is fine/by hand.

Bummer. For another long shot, someone over in the villagerquest Yahoo group had a similar sounding problem on his daughter's van (and also planned to replace the TPS), but he first checked and found the transmission fluid was two quarts low.
Sounds a bit dubious to me, but I'm no mechanic, plus it's another cheap thing to check before paying a shop for a diagnosis. Oh, you may want to recheck the harness connections "at both ends" of the TPS.

Thanks, Tranny full. TPS plugs OK/plugged in but I can re-check them.
Not sure where to go from here except the FPRegulator. After that then the shop I guess, BUT, if you can't hook a scanner up to it then they will be doing the same thing as me but charging more for parts/labor.

Did you ever get the problem fixed? I am having the same issue and have replace the TPS as well. Also, my 99 Villager is shifting incorrectly. Have replaces the TPS, Mass airflow sensor, plugs, wires, distributor and fuel filter per mechanic recommendations. Any new ideas?

Yes, the MAFlow Sensor was very dirty and it also caused the tranny to shift weird and wouldn't go over 15mph. Now it runs like a new car. I put it on a computer and the computer came up with the TPS O2 and a few other things but it was the MAFlow that was triggering the problems. You might want to get it put on a computer. Computer cost for me was $68.00 plus labor of 3 hrs, he only charged me $102.00. Pull and check all your fuses first.
