Well, Boosty. When you're right, you're right. I do need to check the ground connections. I don't wanna, but it'* gotta be done.

I have enough speaker wire laying around to run ground wires to the sensors in question. However, the MAF(suspect) is 183k old and only supposed to last about 60k to start. The EDIS(suspect) is the same story almost, except that it lasts 100k to start. As for evidence of a poor connection, between the EDIS and the EEC harness, I can pull about 5 to 7 ohms of resistance between the three wires that the EEC uses. The grease in the connector to the EDIS is a bit chalky looking, so it'* more than possible that it'* losing voltage there, as well as the main connector under the hood. I need a little pipe cleaner or something to swab all of the holes out, use a little electronics cleaner, and grease 'em again. That'll put that at rest.

The only thing I changed when I had it apart, aside from the trans, which was properly rewired, was the gears. I have a tune and speedcal in place to compensate for those, as mentioned earlier. One thing I noticed last night was that when I had the speedcal unhooked from a power supply, the car thought it was rolling 66 mph when idling in manual 1st. Maybe it'* nothing. i don't know. I'll have to check that out too.

*edit* So you know, the computer calculated a speed reading of 66 mph, but the speedometer showed no movement at all.

I wouldn't get overly excited about the speedo, although it the computer sees 66 and the speedo see'* nothing at all.. electrical gremlin.

In the bonne.. that either needs to be programmed or fixed via reluctor wheel and speedo recalibrator. Something tells me we need to think that over more.

Get the electronics cleaner.. get the dielectric. Git'r done. At the least you can say you know it isn't causing part of the problem.

Update. Maybe not the answer, but a step towards the end result.

Recall I had a P0400 code, EGR Flow Circuit Malfunction, and I also had an issue where my TPS was reading 20% throttle at 0% throttle. I just noticed during my lunch break that the TPS and the EGR Pressure sensor both share ONE wire! Hmmmmm.... Methinks maybe this pressure sensor(which is dangling loose off the back of the TB as a bolt fell out that held it) could be causing feedback into the TPS, giving it a 20% throttle reading? When I did my voltage measurements on my TPS, I did it KOEO. Once it'* running, the EGR is supposed to be functioning, which may be why my TPS value is buggered. So maybe if I replace that sensor, I can see a 0% TPS reading from digimoto? I don't know, but share your thoughts!

Rule out everything you can.

Like we discussed on the phone, deal with that EGR code. Then see where you stand.

Still sittin on my thumb at this point. I need to rip the intake off so I can work it over and pull my EGR crap out.

Didn't tear the car apart, tried a new ignition system, as well as a new MAF, gained nothing other than narrowing down what is actually wrong. Strongly suspecting the EGR now as it'* directly wired with the TPS sensor. Got a replacement DPFE coming to see if that fixes it. It'* literally got me stumped.

Load still is 30% +-3% disconnected the tps sensor to get a 0 reading, no change in load, disconnected maf and no change in load. Only thing left is the crank position sensor. Additionally, shift solenoid 1 is constantly receiving 12v in all gears, including park. Leads me to believe the computer is telling it due to the insane load value. Possibly a misset MLPS as well. I will check it out soon, and probably put my old, known good MLPS back on. Hoping against hope...

Doug...think of me and the various motor failures of late to keep your spirits high...if that fails..grab a beer.

You'll get it..and then ...the lesson you will have gained...will be priceless.

This is another shot in the dark.


Is there a sensor on the transmission that tells the computer what gear you have the car in ?

If the computer thinks the car is in low w/electronic tranny it won't shift.

I understand some of the computer things in cars but I so prefer them on my desk. (where I can smack em).

Is there a way a tester can tell you what gear the tranny is in ?

You said.
Had a custom chip burned to account for the 8 tooth output shaft, and the new gears.

Are you sure it was done correctly ?
