Driving Issues
Hey Guys,
I have been having an ongoing problem for quite some time, its kinda tricky so ill try to be as elaborate as possible. I put the quick change in a year or two ago and although it worked it made my car shift funky especially at higway speeds so I took it out and rewired the plug back to normal. Since that time I have had issues with my car running right; the car wants to jump a gear and rev out; dependant on where my TPS is set. Ive been messing around with it for years; when my TPS is set normal the car shifts fine until around highway speeds; then around 65-80 MPH the car just starts reving out until I tap the brake. If I set the TPS different (Put it almost all the way down) the car drives well at highway speeds but It doesnt shift right while driving in the city it misses a gear at times and doesnt want to shift smooth. I had issues with the car starting after a vacum leak as well; however, after one long drive of the car revving at highway speeds, that problem resolved. IDK what to look for; I pulled engine codes and I believe it read temp coolant sensor, O2 sensor and TPS; but when I corrected the TPS those codes went away. Does anyone have any clue whats going on; its so frustruating that Im debating selling the car and getting a legacy; I dont want to, but this is very hard to put up with. any help appreciated

Re: Driving Issues
Coolant temp sensor (CTS) is frequently associated with starting problems, and fairly easy to replace.
For the TPS, if it just can't be adjusted to work normally, then you should try a new one altogether (or a known good used one). I would also suspect the wiring where the QC was. I imagine that if the TPS wiring is messed up just right, it could have some symptoms like a bad TPS.

Re: Driving Issues
What voltage are you reading at the white wire?
It should be 0.48V. Subaru says between 0.45-0.55.

Re: Driving Issues
I haven't measured it, I don't have the tools. Im just playing with it and seeing th symptoms. Right now I have it in the factory position where it was marked and it all drives fine except for when im doing 30-45 mph then just s slight tap of the gas causes a quick shift, not normal, I've checked the wiring many times, that was my first thought

Re: Driving Issues
Please buy a digital voltmeter/multimeter.
At no more than $20.00 for a cheap one you can save your transmission.

Re: Driving Issues
It you're not measuring the voltage, you're doing it wrong. A multimeter is seriously like $15 at walmart man. Harbor freight has them for even less actually: http://www.harborfreight.com/catalog...t?q=multimeter
What you can do is stick pins in the wires, and then attach the multimeter clips to the pins to measure the voltage. When you pull out the pins the wire and sheathing should be fine. Good call on looking at the QC wiring too. You wrapped it up good too right? When I did the 6-speed swap to my (late) white car, I ended up with a bunch of electrical tape where the QC had been.
