1994 Chevrolet Astro

I BOUGHT A SET OF 119679 FIREHAWK INDY 500 P225/70R15 TLRWLPS TIRES FROM A FIRESTONE DEALER IN WARNER ROBINS GEORGIA. THE 1ST TIME I TOOK IT TO THEM FOR BOUNCING AND THEY REPLACED 1 TIRE SAYING IT WAS CAKING,I HAVE KNOW IDEA WHAT THAT MEANS. I AM HAVING PROBLEMS WITH A COUPLE OF THE TIRES STILL BOUNCING LIKE AN OUT OF BALANCE TIRE. I WILL BE TAKING THE VEHICLE BACK TO HAVE THEM CHECKED AGAIN SOON. IT JUST SEEMS A LITTLE STRANGE THAT I GET 4 TIRES AND AM HAVING PROBLEMS WITH WHAT SEEMS LIKE ALL FOUR TIRES. IS THERE A PROCESS THAT CHECKS TIRES FOR DEFECTS ? MAKES ONE WONDER WHY FIRESTONE IS HAVING ALL THE PROBLEMS WITH THERE TIRES. THANKS FOR LISTENING. WILLIAM B.COLEMAN. *NM

FOR ALL OF YOU 1994 CHEVROLET ASTRO OWNERS AND ANY OTHERS THAT HAVE THE OLDER 4.3L VORTEC ENGINE. I HAVE THE SOLUTION TO YOUR LEGR VALVE CARBON CLOGING PROBLEM. MY 1994 EXT VAN HAS 150,000 MILES AND I HAD BEEN GETTING THE ROUGH IDLE AND STALLING WHEN AT A STOP LIGHT PROBLEM. IT HAS DONE THIS BEFORE TO ME EVERY 6MONTHS OR SO AND I JUST PULLED OFF MY EGR VALVE, KNOCK OUT THE CARBON CHUNK THAT IS STUCK IN IT AND 20 MIN LATER IM ON MY WAY. WELL IT HAS COME BACK BAD AND IT IS CLOGING EVERY 20 MILES WITH LOTS OF CARBON CHUNKS. CHEVY TELLS ME THAT THE LOWER INTAKE NEEDS TO BE EMOVED AND BEAD BLASTED TO REMOVE THE CARBON BUILD UP. I DID SOME RESEARCH AND THERE WAS A EGR RECALL THAT THEY WERE SUPPOSED TO TAKE CARE OF THIS CLEANING IF IT HAPPENED THE 1ST 7 YEARS OR 75,000 MILES OF THE VAN. WELL THEY WONT DO IT FOR ME AND THE DEALER WANTS $500-$1000 TO DO THIS. I FANALY FOUND THE SOLUTION TO THIS PROBLEM THAT EVERY CHEVY OWNER THAT HAS THE 4.3L VORTEC ENINGE. THIS IS CALLED THE KLEAN SCREEN. IT IS A REPLACEMENT EGR GASKET THAT HAS A HIGH TEMP SCREEN AT THE EGR INPUT OPENING THAT WILL STOP LARGE CHUNKS OF CARBON FROM ENTERING THE EGR VALVE AND WHEN IT GETS WARMED UP THE SCREEN WILL BREAK THE CHUNKS UP INTO SMALL PEICES THAT WILL PASS THE EGR POPPET. THEY COST ABOUT 13.50 EACH AT AUTO ZONE AND THE COMPANY IS NAMED TOMCO INC. WWW.TOMCO-INC.COM. IT HAS BEEN 1 WEEK SINCE I HAVE INSTALLED THE GASKET ON THE ORIGINAL EGR VALVE THAT CAME WITH THE VAN NEW 150,000 MILES AGO AND IT RUNS GREAT SO FAR. TH GM PART NUMBER FOR THIS GASKET IS 2-1357. I BOUGHT MINE AT THE LOCAL AUTOZONE BY MY HOUSE IN VIRGINIA. YOU CAN ALSO BUY RIGHT FROM THE COMPANY AT 10.50 EACH WITH A 5 ORDER MIN. GOOD LUCK EVERYONE WAYNE JORDAN. *AK
