    1uz over heat issues

    So i havnt changed the thermostat, but what i did do was remove the radiator shroud that i made from a piece of aluminum. I had it there for directing more air flow to the radiator,but i think i may have been causing heat issues. Not sure will re Evaluate as the temperature outside goes up...

    1uz over heat issues

    thank you for the technical information . to make the fan location clear. the fans are in-between the radiator and the engine not the radiator support. they are pushing air thru the radiator and a/c condenser and out the front grill. i am going to pull the thermostat this morning and check to...

    1uz over heat issues

    the fans are behind the radiator , i did 100% verify the fans are pushing thru the radiator. i have a replacement thermostat. i wanted to try the trd 70 degree or the mits 76 degree option ,but haven't ordered either. I do have a ls400 thermostat, but skeptical it will change anything especially...

    1uz over heat issues

    So 95 ls400 is overheating at idle. I have a 3 core radiator , and i did have just a 15" electric fan bolted directly to the radiator. It did ok ,but on hot days is would get up to 240f at idle. So i got a mishimoto dual fan setup with a shroud thinking it would help direct the heat better. Well...

    Rear end keeps puking

    absolutely! i was thinking of using a expedition rear end so i can have the strength of a ford 8.8" and still have independent travel. i may in the meantime try using a torsen kit. I've seen they are fairly affordable

    Rear end keeps puking

    So i am running a 1uz with a w58 gearbox and a 85 celica supra rear end with 3:73 gears. All seems to be good ,but the rear end keeps puking out of the vent and ive been changing the fluid in it regularly due to excessive friction material. I do plan on running a ford 9" eventually, but in the...

    5 speed swap how to delete automatic codes 1uz

    I take that back drove the cressida to the shop and the e solenoid got super hot so i removed it so it didnt smoke the ecu. Guess im just livin with the trans codes till i get a standalone ecu

    5 speed swap how to delete automatic codes 1uz

    So i checked it out this morning and solenoids a and b are the affected circuits by the resistors . I grounded one side of the lead with my test leads and the other side was in the pins of the connectors and as soon as i started it up it would smoke. Solenoid e lockup is fine tho . Also there...

    5 speed swap how to delete automatic codes 1uz

    This is a non vvti engine. Its a 90 long block with pre vvti obd2 eletronics. Also. One of the resistors smoked yesterday so im going back to the drawing board

    5 speed swap how to delete automatic codes 1uz

    So i bought some resistors from the local electronics store. It costed me a whopping $2.05. The shift solenoids a and b have the same ohm resistance value of 11 to 16 so i got a 13 ohm resistor . The a and b are triggerd by b+ voltage amd the valve body grounds the circuit. So i hooked my test...

    5 speed swap how to delete automatic codes 1uz

    So the saga continues... the 1uz swap has been a wonderful learning curve for me . ive learned so much about wiring through this build. So far i have got all the Ecu codes engine side off of my vehicle thru using the factory diagrams alldata, mitchell, and many helpful comments through this...

    Egr Delete Check Engine Light 95 Lexus1uz

    So after research, i have learned that there are 2 different ways to get rid of the check engine light for egr delete. Ether put a resistor on the egr temp sensor circuit obd1 only , or plug the top part of the egr valve back in obd2. I deleted this egr a long time ago, so i lost my egr valve...

    loss of power no throttle response after driving on highway for 30+ mins

    while vehicle is running the FPR never produces more than 150mv , the testing says the FPR should put out 9-14 v for 60 seconds then drop to 0-3 volts . So im guessing the fuel pump is bypassing the stage from light load to heavy load and its always running at heavy load?? Also i might add i am...

    Egr Delete Check Engine Light 95 Lexus1uz

    So i am writing this to clarify whether i am on the right track or not . From what i have read on the Egr valve and its functions with the ECM PURPOSE The Exhaust Gas Recirculation (EGR) Temperature Sensor is used for on-board monitoring of EGR function. OPERATION By measuring the...

    loss of power no throttle response after driving on highway for 30+ mins

    the only codes that are stored are the rear 02s ( not hooked up) , egr (deleted) and trans solenoid codes ( it has a w58 swap) before i hook up the scope, i have a digital gauge that is hooked to the obd2 port. im going to take a long trip and monitor the tps . I feel that this is the cause of...
