1999 TOYOTA 4RUNNER Engine Problems

VALVE COVER GASKET FAILED HEAD GASKET FAILED, 3RD CYL AFFECTED. *TR

WENT TO GET AND OIL CHANGE, WHEN MY CAR WAS RETURNED THE CAR STARTED TO VIBRATE VERY TIME I WAS AT A STOP SIGN, THEN THE CHECK ENGINE LIGHT CAME OVER 12-13 TIMES ALL WITH DIFFERENT CODES... MY CAR KEEPS STALLING AND RESTARTING... THE BRAKES IS MAKING A GRINDING SOUND JUST GOT THE BRAKES DONE... FUEL INJECTION CLEANING ... AND THE RIGHT REAR LIGHT KEEPS MALFUNCTIONING EVEN AFTER I'VE CHANGE THE BULBS ON SEVERAL TIMES...

THE VEHICLE STALLS, INCOSISTENTLY, BUT, ON A FREQUENT BASIS, AT ANY GIVEN TIME, THEN WILL BE FINE FOR A LONG PERIOD OF TIME. IT EATS BATTERIES. I'VE HAD TO REPLACE THE BATTERY EVERY YEAR. A LOCAL AUTOMOTIVE ELECTRICAL SPECIALIST REPLACED THE B+ CABLE FROM THE BATTERY TO THE STARTER, AND THE PROBLEM WENT AWAY FOR A YEAR, BUT, HAS SINCE RETURNED. I RECENTLY UPGRADED TO A BATTERY WITH MORE CRANKING WATTS, AND HAVE EEN IMPROVEMENT. HOWEVER. THERE'S THE ISSUE OF THE HESITATION, JERKING, AND LOSS OF POWER, WHEN TAKING OFF AFTER 1ST START OF THE DAY, REPLACED PLUGS, AND BATTERY AND DID A TUNE - UP, BUT, IT MADE NO DIFFERENCE. VERY DANGEROUS AND HAVE ALMOST BEEN INVOLVED IN ACCIDENTS MULTIPLE TIMES, AS A RESULT, INCLUDING DYING WHILE TOWING A TRAILER, SMACK DAB IN THE MIDDLE OF A 4-WAY INTERSECTION OF A TRAFFIC - CHOKED COASTAL HIGHWAY IN THE MIDDLE...
