I recently replaced caliper and pads also bled the brakes twice but I am still having my passenger front brake/rim heat up beyond touch i have to wait for them to cool down before working on them?
ok, now ive actually got an '89 not a '90 but they dont have that option. my blazer is 4x4 but the front end is not working. the transfer case does engage but only the wheels dont get any power. plus i can only get into four high, i cant get the 4x4 into four low or neutral.

4.3 vortec blazer vin W
have replaced IAC three times in past 2 years
starts and runs good 85% of the time
check engine light comes on with code #32
starts running rough,don't dare shut it off
does the PCM control the IAC if so where is it located
where is the egr sensor on a 4.3 chevy and how do i take it off/?
I have a 90 S-10 Blazer 4.3l and recently had a rough idle and stalling out after a few minutes of run time. The check engine light came on at highway speeds and I pulled a code 32 of the ECM , reference back to a faulty EGR circuit. The EGR was dirty and plugged beyond cleaning so it has been replaced.

Did a tune up - cap, rotor, plugs, wires as well. The rough idle is gone and it runs at idle fine. I power brake it in drive and reverse and it does not seem to want to stall.

The only time it stalls now is after reaching above the speeds of 15 mph or more and only stalls when I brake at lights. Did another code check and found nothing in the system. Set the e-brake and power braked it again and still only stalls after reaching above 15 mph. I know it seems to be getting enough fuel if it wont die after power braking it. What else could be cause a stall only when reaching above 15 mph and braking ?

How do tell if the engine is running rich? I get low fuel mileage 14mpg. The engine is a V6 Vortec. Can the fuel mixture be adjusted?
