A few technical questions Options

[hitbyastick]

Hello everyone,

Is the car supposed to idle at 1800RPM until it heats up? Then it goes right down to 1000. I'm assuming that's the aux. air regulator closing, although 1800 does seem high.

What's the fuel pressure supposed to be? My old FPR would only stop leaking if it was fully closed so for a while it was running at 70psi, which I know is too high. I replaced it and it's right around 35.

I think my TPS is not working properly. The car runs fine, but if I'm driving on the freeway and then just ease my foot down a little bit more on the accelerator, it misses a beat or two. When I give it a lot more gas (say I floor it) this does not happen. When I move the throttle by hand with the ignition on, the TPS "clicks" about 10 times. I'm assuming it's worn out.

I have Yokohama AVS (195/65/15) in the fronts of my car and they are nearing the end of their life. I love these tires but I know I can't get any more. What is comparable?

Thanks a lot,

Mr. Christoph
