Re: Temperature slider seized up - where to find replacement cable?

Are you certain that it is the cable and not the actual water control valve? It could be the valve or a lubrication problem since it still works, just difficult to actuate.

Re: Bad torque steer with new wide tires

I haven't had the alignment checked since putting the new wheels and tires on. Are there ways to help compensate for the scrub radius change?

Re: Camber and pulling issue

This will be hard to do since they are directional tires. I do have another set of tires and rims around that I'll put on and see if the car pulls the same with those.

Shocks are not leaking and have about 30k miles on them. The rack does have a very slow leak, maybe a tablespoon a year, that is evident by PS fluid on the bellows. I'm wondering if the colder...

Re: AFR at idle issue

Do you have either a narrow band or wide band oxygen sensor installed? I would recommend using the Closed Loop parameters for AFR control as opposed to fuel tables.

Re: Hondata Traction Control Help - H23 VTEC Turbo 400whp

I have quick spool disabled. The over boost in 1st gear only happens when TC is enabled so I think it's caused by retarded timing. RPM is increasing so fast in 1st that I think it over boosts before...

Quite possibly the o-ring that seals the oil cooler against the block has failed.
