Two Problems

joburnet · #1 03-20-2007, 09:00 AM

1. Still stalling once it gets warmed up. I took off and cleaned the throttle body and IACV and replaced the MAFS. I have a leak in the radiator and it won't hold pressure, any chance that is the problem? Is this something that a vacuum leak could cause, it only happens when it's warm and I would think a vacuum leak would cause problems all the time.

2. Just replaced the rear wheel bearings and now I can feel the ABS come on when I come to a stop. It's very slight and doesn't affect my stopping at all but I don't like feeling it when I don't need it. I'm thinking the machine shop broke something or more likely left it dirty, any other ideas?

1. I have never heard of a radiator leak causing stalling, but you should fix the radiator because it could lead to a whole mess of more costly problems. SVXi do not like heat! With all the electronics under the hood, heat is the enemy.

2. My money would be on dirty. A good under carriage spray at the car wash was just the ticket to clean up debis from my brakes and prevent my ABS from pulsing.

A vacuum leak could become a problem once the car is warm and the idle drops down. The leak could cause it to drop too far and not keep the idle.

Where should I be looking for this kind of leak?

Since I found out that the radiator has a hole I've only run it until it warms up. There is still plenty of fluid in it, just a hole at the top so it won't hold pressure. I plan on doing a quick patch and then replacing the radiator when I have everything else figured out.

I think it's fixed, I sprayed some throttle body cleaner down the tube to clean the AACV, I think that's what it is, and it seems to have solved the problem. Just got a MD inspection on it and it needs new front rotors, too thin, and a front wheel alignment and I'm good to go.

Anyone know what the spec is for the front alignment in Feet Per Mile?

Going to be either a damaged tone wheel or the gap between the ABS sensor and tone wheel is incorrect. Last I can remember the gap should be between 0.7mm and 1.0mm.
