QUOTE (Julio @ Nov 7 2009, 12:43 PM) still looking for a fix on this, getting brake light on traction control lamp on and abs light on also message service stability control sys. All data has little to offer in isolation though it says all these codes are controlled by the ebcm, I have good grounds pins f & g on the EBCM connector. Would the Steering position sensor cause the brake...

QUOTE (Jims_97_ETC @ Nov 6 2009, 03:03 AM) GM has been making DOHC 4-valve engines for daily drivers since the Quad 4 came out in 1988 so they have the formula as well as anyone. I expect that we will be seeing 4-valve engines for a long time. Sadly the Quad 4 was another example of a head gasket/head bolt failure just waiting to happen. Most of those engines died before 80,...

Yes, its normal, dropping the selector to 3rd increases the RPMs, there by turning the WP faster, there by pumping more coolant, through the radiator. I have witnessed this myself.. By the way, its a common misperception that a water pump goes bad, in that it PUMPS LESS, and that is NOT true at all, water pumps don't go bad in their function they go bad in terms of their ability to hold...

I need to drop my carriage to timesert/stud the block. I am thinking of making a dolly the size of the carriage about 8 inches high, out of 4 by 4's with wheels on it. I plan to drop the engine carriage on the dolly with the bolt system and raise the body of the car off of the engine/tranny assembly with an engine hoist and roll the carriage into the garage. What do you guys think of ...

How about the standard tip: checking for codes? Sure, it is possible to get better gas mileage if you skip emission control systems (like the cat), but then you also have to program the PCM accordingly. Unless you have reprogrammed the PCM (few people would pull that off, I think), it is still programmed for having a cat, which means that it will try to maintain the stoichiometric ratio of...

I see the same thing you report; http://parts-catalog.acdelco.com/catalog/catalog_s earch.php shows both sets as good for your vehicle.

That sounds low to me, for that matter anything below 12 volts for any length of time especially at highway speeds.

QUOTE (Jims_97_ETC @ Nov 5 2009, 04:41 PM) I think any of the oils you mentioned is OK, but be careful about anything with a number higher than 30 in the top number. Oil that is too thick when hot may result in stuck rings. My GM manual is pretty firm about using only 20W-30 or 5W-30, and never using 2W-40 or any other oil with 40 or higher in the top number. It sounds like a ...
