1997 Toyota RAV4

RAV 4 TOYOTA 1997-WAS UNABLE TO DRIVE MORE THAN 30 MILES WITHOUT THE RPR INCREASED WITHOUT CONTROL, TRANSMISSION AND ENGINE BECOME EXTREMELY HOT, FLUIDS WERE DRAINED . CAR SENT TO DARCARS TOYOTA THERMOSTAT WAS REPLACED, AND NOW FACING SEVERE TRANSMISSION ISSUES, BECAUSE LACK OF RECALL RPR 'S ISSUE VERY DETRIMENTAL AND RISKY . *TR

EACH TIME YOU STOP AND THEN PUSH ON THE GAS PEDAL IT STICKS. YOU MUST PUSH HARDER THAN USUAL TO GET THE CAR TO MOVE. BUT THAT MAKES THE CAR LURCH FORWARD AT A GREATER SPEED THAN YOU WOULD LIKE. IN TRAFFIC THIS IS VERY DANGEROUS. THE DEALER SAID IT WAS THE FUEL INJECTORS , BUT I THINK IT,S IN THE LINKAGE OR THE WAY THE PEDAL WAS MADE THAT IS THE CAUSE OF THE PROBLEM.*AK

WHILE DRIVING DOWN THE ROAD COMING TO A RED LIGHT CONSUMER TOOK FOOT OFF GAS PEDAL, AND VEHICLE STARTED TO ACCELERATE, CONSUMER TRIED TO PUT ON BRAKES AND PULLED EMERGENCY BRAKE, CONSUMER SWERVED HITTING A SCHOOL BUS THAT WAS CROSSING IN FRONT OF VEHICLE. TOOK TO A MECHANIC, AND HE SAID IT WAS A DESIGN FLAW, A COVER THAT COVERS ACCELERATION CABLE ASSEMBLY, IT FELL INTO PLACE AND LOCKED ACCELERATION OPEN. *AK INVESTIGATION BY INDEPENDENT GROUP INDICATED THAT THE ACCIDENT WAS THE RESULT OF FAILED/ STUCK ACCELERATOR. *YH

THE IDLE AIR CONTROL (IAC) VALVE CONTROLS THE IDLE SPEED BY METERING AIR AROUND THE THROTTLE PLATE, UNDER CONTROL OF THE ENGINE COMPUTER. THE IAC VALVE ON MY VEHICLE STICKS WHEN THE ENGINE IS COLD, REQUIRING ME TO HOLD A SLIGHT THROTTLE PRESSURE TO KEEP THE ENGINE RUNNING AFTER CRANKING. ON SEVERAL OCCASIONS, AS I WAS EASING THE CAR OUT OF THE GARAGE AT IDLE, THE IAC VALVE UNSTUCK AND CAUSED THE CAR TO SURGE AHEAD. THIS IS VERY ABRUPT AND DISCONCERTING, BUT IT HAS NOT (YET) CAUSED AN ACCIDENT. I HAVE A TOYOTA FACTORY SHOP MANUAL, AND I MADE THE RESISTANCE AND VOLTAGE CHECKS CALLED OUT FOR THE IAC VALVE; ALL WERE SATISFACTORY. SINCE THE VALVE'S COILS APPEAR TO BE OKAY, AND THE ENGINE COMPUTER'S COMMANDS APPEAR TO BE OKAY, I CONCLUDE THAT THE IAC VALVE SIMPLY STICKS WHEN IT IS COLD. THE PROBLEM GOES AWAY WITH A WARM ENGINE. THIS PROBLEM BEGAN ABOUT SIX MONTHS AGO, AND IT NOW OCCURS AT ALMOST EVERY MORNING START. I COMMUTE ABOUT 25 MILES PER DAY. *AK
