95GS300

Guys, on a quick note, if the 'N' Idle speed is around 500 & 'D' around 200, would that be one of possible route causes of Performance degradation? I find it very sluggish and it takes ages to cross 60km, the responsivness is really bad. However, once it crosses the 100km, the response becomes gradually better but only during the higher speeds.... Any idea? Thanks in Advance! I get the EML after crossing 1000RPM, and use 91 type fuel!

Hi, just found some old notes in my work shop, and should help u.For models fitted with Toyota TCCS fuel systems;FAULT;Hesistation/poor acceleration;COMPONENT CHECK SEQUENCE;1. signal from self-diagnosis;2.air intake and vacuum systems for leaks; 3.injector valves;4.throttle valve/sticking/position/linkage/dashpot;5.air control valve;6.auxiliary air valve;7.fuel pressure/delivery rate/regulator;8.injection system conections/wiring/relays B) Phew!! that was awesome .... rich contents here... I dont know how to thank you but really it was great to receive the replies.... just to be on safe side before asking the mechanic to have a look into these potential problems areas, if its possible to get the clarification that the Spark Plugs, type of Fuel (I use 91, instead of 95) or Gear Box / Tranny? has got nothing to do / less to do with the power accellaration / hesitation, sluggish response? Also, on a quick note, if the 'N' Idle speed is around 500 & 'D' around 200, would that be one of possible route causes of Performance degradation?

cool. maybe ur sparkies need changing tho? Sorry being abrupt... didnt want to start a new thread...My Q being a newbie here that would the Spark Plugs be responsible for Sluggish Start as mine takes alot of time to move as I often floor the gas pedal and by the time it reaches 100km mark becomes steady... Could it be due to some AirIntake or Sensor malfunction issue? I get the Engine Mgmt Light on! I did the ECU reset yesterday, the car jump started for a couple of min went like a powerhorse but the moment the EM light came on... the power lost.... and it drove very sluggish!! any advise would appreciated whole heartedly. Thanks in anticipation.

Guys! I am a newbie, drive GS300 95 for a couple of years and simply in love with this beast.... The engine sounds fine at idle speed no missfiring, no viberation... etcthe problem recently happened was the car wont pickup as normal once stopped, takes good 50 sec to cross 100km then gradually goes normal? the Engine Mgmt Light is on.... The engine idle speed is at around 500~600RPM without AC and goes down at 200 if in D mode but idle. I tried resetting the ECU, the pick up returned for few min but then again the Engine Mgmt light came on.. and the performance dropped way below! Any ideas or suggestions? are wellcomed....? could it be due to Spark Plugs or Throttle Assembly wiring?? or any sensor? I couldnt find a mechanic with Code reader here in this part of the world.. (United Arab Emirates)..Please help!!
