I think I found the problem (High idle)

For a year I've been searching, poking, troubleshooting and bothering a lot of people on this board (thanks for all your help) on a code 32 (evp, egr valve problem) This is where it gets Interesting. To troubleshoot this I had a high idle up around 1500rpm Come out of the store turn the motor back on and the idle was fine never could figure this out. Run the motor get on it a bit and it would flash a code 32. Changed the evp,egr valve no help. watch the vaccume while driving even the voltage off of the computer the voltage would never go below .67. I could never get a answer to this problem either. One day on my way to work the motor starts to buck real bad I need a saddle. I check the codes it was a 63 low voltage to the TPS. I had a spare so I changed it, NO HELP It Bucked all over the place. I checked the voltage while driving, the voltage droped like a rock,I never saw a tps go negative voltage before. When I changed the TPS I cleared the computer when I had the second code 63 i checked the codes the code 32 was gone only the 63 was there. I watch the evp voltage with a meter while driving, It was a miracle the 32 was gone after a year and it was acting like it should, voltage change go down on the peddle and the voltage would go up it never did this before. I got another TPS changed it again and got a code 63 and the voltage went negetive again even stayed at 0.0 for a while. This has got to be a computer problem I'm going to change the ecm one proble does not fix itself start another one and be three TPS's no DAMM way. The computer can't keep up with the info I'm getting a new one tomorrow I'll let you know how I make out. OH the high idle went away When it runs it idles great like new ....... Sorry its so long this is a years worh of crap Later

No Book Jerry I get it form hanging around here. I started the motor and did a wiggle test to see if the voltage would go wackey, It stayed solid. The weird thing is it will start out ok it will run. I'll go about 5 to 10 miles and then it will start Bucking real bad, It so bad it can make the CD skip in the player This is when the voltage goes to zero. I will do the test you suggested thanks foe the reply JOE........ Also my Gas mileage was for crap. My fuel regulator went it was something like 68 pounds for god knows how long I looked at the o2 sensors while running before I replaced it and after the voltage reading while bounceing back and forth never changed .3 to .8.

Thanks JD If it starts again thats where I'll go. So far all day it hasn't done it and the idle is GOOD, I never had a good idle I Forgot what it feels like. So far no check engine lights either.
