A few things about my supra...

(87 7mgte)

1. Recently, I started noticing that while driving with my headlights on they will dim for a second. It's totally random and doesn't happen too often, what could the problem be?

2. Is there any way to disable ABS?

3. The stock blow off valve recently started making noticable noise when it "blows off". It sounds like an aftermarket BOV now but it never used to make this noise... could it be broken?

4. The passenger window will always go down, but sometimes it won't go up. I have to press the button for it to go up many times until it decides to go up. The window button on the passenger door doesn't work either (and no the window lock option isn't turned on). What should I look at to fix this?

5. Ever since I changed the timing belt, valve covers, and cam seals, the supra will backfire sometimes when I let off the throttle and just cruse. The supra also smells funny when it's running. Are these the simptoms of running too rich? What do I do?

6. When I pull the emergency break, I hear a loud "clank" sound just once. What could the problem be?

Thanks in advance.

4. Your switches are probably bad and need to be replaced. I had a similar problem with my door lock switches

5. Have you checked the timing?

Is there a way how I can check it myself?

5. Have you checked the timing?

After I had put the timing belt back on I had taken the car to a mechanic. He said everything was ok except for my alternator belt which was loose so we fixed it.

Should I take it somewhere else or learn how to do it myself?

for the window check your passenger side switch. i have the exact same problem in mine and it turned out to be the passenger side switch a pretty easy fix

why in the hell would you disable abs?

My rear speed sensor is broken and is causing my braking system to act horrably until it automatically shuts off the ABS. Insted of fixing the expensive speed sensor or driving around with bad brakes until ABS shuts off, I just want to disable ABS as a whole.

If you have an ABS, you will have conventional brakes by default ehen there is a malfunction. Get your car fixed.

3. The spring could be getting soft.

6.The cable snapped, or the rust holding it did.
