    Alternator voltage drops to 10.4 with headlights on 88 cressida

    So my 1uz swapped cressida has this weird issue. The voltage when either pressing on the brake pedal or turning on the headlights , drops the voltage down to 10.4 v when running . it stopped doing it then did it again. I do have an aftermarket electric fan and a 1000 watt stereo system, so i...

    New Used ECU issues! I think i hydrolocked my engine with fuel

    it seems to be fine now , i may have another issue with #5 , but atm its running great, with the 3rd replacement ecu. Only thing i notice is it has a light gray mist when cold , but after its warmed up its all good

    New Used ECU issues! I think i hydrolocked my engine with fuel

    i will probably do just that. im assuming the drivers were bad in the old computer , as it hydrolocked the engine but with the new engine it runs fine , i wonder if it was a combination of the two both stuck #5 and an ecu . maybe thats why the engine runs a little rich when cold

    New Used ECU issues! I think i hydrolocked my engine with fuel

    So i wanted to give an update on the engine flooding issue. I received a new used ecu and cleaned out all my cylinder of fuel. i cleaned the spark plugs and reinstalled them. I noticed that the #5 cylinder was full of fuel when i took out the plugs. All the plugs were black and wet with fuel...

    New Used ECU issues! I think i hydrolocked my engine with fuel

    So update on engine issues. the new ecu didnt change much, i still idles right , but it still has smoke coming out that smells like fuel. i havnt tried driving it to see if this is just residual fuel or what . Injectors maybe? . #6 cylinder was flooded when i pulled all the plugs out. it was the...

    New Used ECU issues! I think i hydrolocked my engine with fuel

    i dont have the rear 02 sensors wired , but the front ones appear to work fine. I Don't suspect o2s to blame . it didn't affect the drivability prior to the 1st computer. i replaced the old computer due to it losing m-rel power out. Im more concerned the engine hydrolocked when i was trying to...
