Agreed! I had to go out and buy another one since I left my old one in Ohio.

I went and double checked the TPS after downloading the BGB, and verified the E2 and VTA were the points I needed to be checking. I got about 118 ohms for about a half of a second, and then it went to an infinite reading. It stays infinite all the way though the throttle being opened completely.

My vote is that it's bad.

Alright, here's the readings, taken at 69*F:

VTA + E2 (Spec: .2-.8k) - Reading: 416k
IDL + E2 @ .35mm or .0138" (spec: 2.3k or less) Reading: 110K
IDL + E2 @ .59mm or .0232" (Spec: Open) Reading: 68k
VTA + E2 @ fully open throttle (spec 3.3-10K) Reading: 4.39 @ 20K (Couldn't get a reading on K)
Vcc + E2 (Spec 3-7k) Reading 5.03 @ 20K (Again, couldn't get a reading on K)

Hey guys! I'm sorry I forgot to get back with you all on this. I got it fired up and timed correctly. Got it back here to Ohio.

I just thought I'd confirm that the TPS WAS the problem! Thank you so much for your help everyone! I'll get some pictures up soon for ya!

So here's the summary:

The motor was smoking thoroughly, so I knew it needed some help. I initially thought it was the valve seals, as it smoked harder when I would let off the throttle on the highway. So I pulled the motor and transmission out (nasty):

Image

I then tore it down, and discovered this:

Image

Yep. Detonation on an N/A. Do I get an award?

Anyhow, I turned the motor into this:

Image

Image

And then put it back in:

Image

Build:

A lightweight flywheel
minor port + polish
.040" bore
NST triflow cams 268* with a 8.33 lift
Adjustable cam gears
RS*R header
EGR delete
all new Toyota hoses, water pump, timing belt, plug wires, cap + rotor, Radiator cap, master gasket set
Custom B-pipe (2.25") into a Magnaflow high flow cat (2.25") + Stock MK2 turbo muffler (not pictured below, but now installed)
Enkei RPF1's wrapped in Azenis RT615's
ST springs + koni struts (not pictured below, but now installed)
Quaife quick ratio steering rack (yet to be installed... still in the box in my closet...)

Currently on order, all new steering components. And will be installed with the quaife rack.

Next purchase- Swaybars!

Most recent picture:

Sadly enough it was only supposed to be a quick $800 project... but... it ended up becoming about five times that. But it's a lot faster now, and a lot more fun to drive. It'll easily outrun and outhandle a second generation MR2. I've got to do a little more fine tuning with the adjustable shocks to find the right stiffness for them to match the springs rates.

Oh, and here's an old picture with my VERY heavy boat anchor 17" wheels:

that's a common failure point on the large port low comp pistons especially when poorly maintained. good job on that.

My friend Bambi had the same problem and now her car is doing almost the same thing. Mine did it too on my Corolla and the tps and ecu were bad.
