Question about 1991 Toyota 4Runner
Hi my dad has referred me to you, could you help me with the problem with my 91 toyota 4runner? It is a V6 3.0L 4x4 automatic transmission. The engine is a 22R-E and the transmission is A340F which i believe is stock for the 91 toyota 4runner. The problem started when i was going out of down and was driving for hours on the highway, before that i didn't notice it so i can't say it wasn't there before then. I was driving down the highway for only a few minutes, maybe 4 or 5 minutes and suddenly my RPM would go up. It was sitting at about 2500 going about 100km/h down the highway then it went up to about 3700 going same speed. I have tried many things to try and fix it, i turned my O/D switch on and off, i also switched into neutral while going down the highway, waited for the RPM to drop down under 1000RPM then switch back into neutral but still went back up to 3700RPM, i also tried to speed up to 120/125km/h thinking it might gear up but did not, and RPM would reach 4200RPM. Also my fuel consumption is outrageous, i am using twice as much as i should be. I getting about 200km on a 60L tank of gas. I have changed my throttle position sensor, and my coolant temperature sensor. I have checked for proper transmission fluid and radiator fluid amounts. It has been hesitating for about a second when i am completely stopped. But does not hesitate every time. Over the last week it has gotten worse, it no longer jumps up while driving down the highway, when i go up to 100km/h it is at 3600RPM almost like whatever was the problem has stopped working entirely. And the hesitation has been getting alot worse yesterday i had it hesitate for about 2-3 seconds. My dad rigged me up a wire with clips/fuses and a button to activate my error codes while driving because i was not getting any codes while i was parked. So while driving at 100km/h i pushed the button to activate the error codes and my O/D light began to blink constantly(no codes) and my check engine light blinked with error codes 41 and 51.
41 is the
THROTTLE POSITION SENSOR SIGNAL--OPEN OR SHORT INtps SIGNAL--tps SENSOR
and 51 is
IDL (tps) CONTACTS OFF, NEUTRAL START SWITCH OFF, A/CSWITCH "ON" SIGNAL TO ECU
WITH DIAGNOSTIC CHECK CONNECTOR SHORTED
--NEUTRAL START SWITCH/CIRCUIT
But i think that #51 was coming up because i was driving and not in park. I have also replaced a donut that was in my exhaust pipe before my Catalytic converter. I think that is about all, if there is anything you can think of would be greatly appriciated, thank you
