not related but traction bleeding question.
vvti: perhaps I can ask you a question while we have your attention here in this thread: 
I'm trying to find out how to manually run the traction motor on the 90LS400 so that the two bleeder traction valves can be used to take out the air. THe manual states that the traction motor shold be run while bleeding. but when I turn on the engine and open the bleeder valves nothing comes out of it. any suggestions ? thanks.
More over, on the 90LS there is only one bleeder valve at the traction actuator. There's not valve at the traction accumulator next to the master cylinder. the 93 and above LS do have the bleeder valve at the accumulators. Does this mean that the 90LS only has one bleeder valve for the whole traction system which is at the actuator below the air intake pipe at the right front of the vehicle ?
thnx in advance.

I will post to your thread as soon as I find out what it's take to bleed the brake system on your LS.

This ends the saga of egr malfunction!
Note however one of the brand spanking new denzo plugs that I removed was broken, although I might of broken at removal or if it was broken in first place I am not sure.. For now (this was at 1 am I am running an autolite which will be replaced, by at least ngk if not another denzo later today after radiator job is done. Ive come to realize that timing belt needs to be replaced, a job that will be done not next weekend but weekend after that. Ill tackle the radiator after the car cools down.

Soaking it wont do anything. That thing was down right filthy... And the pipe compartment where the egr connected too.. looks very restricted when it comes to cleaning it.
At less then 80 dollars fortunately this was not a pricey part to replace.

Ive been having this problem for the last 3 months and I am absolutely ****ing sick of it!!!!!
The car had a hesitation ah stalling at idle and it failed emmisions horribly, barely passing co2 and being about 4 times higher then the limit for NOx.
3 months I spent money on first cleaning and finnally buying and replacing...
Egr Valve brand new. I made 2 cleaning attempts on the old one before breaking down and buying the new one.
EGR Modulator I bought it a month ago...
EGR temp sensor accidentally broke the first one and bought a new one...
Total money wasted at a discount..$300.98 bucks.. plus miscellanios stuff like break cleaners little brushes, etc etc.
I finish my install and go to sleep, I start the car with everything hooked up like it should be and sure enough Like I did absolutely noting, ok hesitation was... slightly less then before but its still there. And 3 times during this whole 3 month process have I gotten CEL 71 to appear.
It hesistates more now when I have it in gear vs not in gear, it idles up and down from about 650-800 rpm, IE Hesitation happens more when in L,2, D and R, vs not as bad when its in P or N. And stutters.
Its driving me crazy I want to pass this ****ing car emmissions already my registration will go to about 2 months expired!@!!!
Tune up was done recently like about 6 months ago at this time fuel filter and spark plugs were replaced, the rotor and dist cap was replaced roughly a year and 9 months ago along with the spark plug wires, which are oem stuff.
Right now I have ran out of ideas in what to do.. Please anyone that knows about the subject what now?
I replaced the main components of egr WHAT could possibly be the ****ing problem now?!?!

I never had overheating issues. Until briefly due to a leak on a heater hose. This car was much more stressful 2.5 years ago, when I made roughly 3 times less then what I do now.
If you over heat check your coolant level first. You probably have air trapped in your coolant system. And or a leak in one of your lines. When working properly the car should stay cool regardless how hot it gets.
