9. Reverse instructions

Ok, I may have left out a couple of steps. I replaced front rotors and pads, both upstream O2 sensors, throttle position switch, brand new torque converter, rebuilt valve body and rebuilt transmission.

Shifts are crisp and the gears no longer slip. Unfortunately, there is still some hunting around 38 mph. we're in the middle of a snow storm here in Chicago so I didn't really get a chance to test the drop out. I did log some data prior to the swap and i hope to log some more tomorrow weather permitting.

Default Nice X Pipe! What did it do to the exhaust note?

How much stuff came out of the air plenum drain caps when you pinched them?

Default A nice muted tone

I put on a Lltek exhaust first and it had a nice rough sound. More like a mustang or camaro. The X pipe muted and rounded out the sound. Very pleasant.

I had major drainage back up in Oct, it fried my ECU. So the shop snaked out the drains. When I pinched them only a leaf or two fluttered out, then I cut the tips off and I hope I never have any problems ever again.

Default Mine is carbon too, are they rare?

Why? I thought if 97 has it all others should have it too. It is VERY light drive shaft, lightest I ever seen.
