    1990 C1500 ABS (RWAL) removal.

    I did this on my 90 model Sierra and now it has rear brakes. I almost rear ended somebody who didn`t signal for a right turn. My truck had no rear brakes because of the failed cast iron valve below the master cylinder. Now has great stopping power.

    Front S-10 Blazer driveshaft problem 1993

    About 7 years ago I bought this 1993 S-10 Blazer from one of my brothers. Somebody had done a transmission rebuild on it and they dropped it on driveway and cracked the trans case right on the servo retainer ring groove. The ring came completely out on my way home from work one day and blew...

    1990 K2500 350 5.7 TBI Stalls in reverse or drive

    I see an unplugged knock sensor. This Throttle body injection system needs to have the knock sensor plugged in or it won`t run for long.

    Oil Pressure issue (Not the switch)

    I have a 1990 GMC 1500 ext cab. When I bought it the odometer read 351390 miles. What a worn out 350 TBI engine. One quart per 100 miles. I had a 1972 350 from a Rally Nova and had it machined. Put Scat rods and flat top pistons with 4cc valve reliefs in it with a new TBI camshaft and...

    1990 C1500 ABS (RWAL) removal.

    I just spent about 40 minutes getting rid of the RWAL on my 90 GMC 1500 Sierra. Had to use the adapter fitting I bought ahead of time. Did not have to bleed the brakes. It has never stopped this good since I got the truck. I think the RWAL valve must be stopped up not letting rears work at...

    S-10 engine dies at red light

    I have a 1993 S-10 Blazer with the 4,3W engine. The engine will sometimes go dead at red lights. It does it whether the A/C is on or off. I replaced the IAC and it helped but it will still cut off at a stop.
