For the most part you all have caught on without this post, but there have been a few habitual offenders that forced me to say this.

    Temperature gauge issues

    Hey all, I recently just boosted my 4th generation Accord and have a head-pounding issue with my temperature gauge. It was acting perfectly fine before I boosted the car and now it is malfunctioning.

    While tuning, Uberdata AND Crome both registered cruising temperatures between 195-197 but my gauge would always read hot. As soon as I'd goose the gas a little, the gauge would drop the the halfway mark. Over the last week, I have replaced the thermostat, the radiator cap, the radiator (with an all aluminum unit), and both the temperature sensors underneath the distributor, I even re-wired one of the sensors because the clip was busted. Not only have I done those things, but it's been bled 3 times using 2 different methods.

    I have a cooling fan running whenever the ignition is on, but the other fan does not come on at all it seems. I'm not sure.

    Has anyone run into the same or similar problem? I'm thinking I'm going to wire the other fan to run constantly as well and replace the other 2 sensors. Aside from those things if it doesn't work I'm fresh out of options. I appreciate any comments in return, thanks!

    I'm going to reground the motor in 2-3 spots and wire the fan to stay on constantly. It seems that the increased engine flex from the front torque mount removal is causing bad connection to a few of my ground straps.

      the actual temperature gauge on the dash does not read from the ect. There is a little one wire sensor on the head, under the distributor that sends the signal to the gauge on the dash

        Yea I know, which is why that was the absolute first sensor I replaced and the only one I rewired.

        I solved the problem today, there was a broken/loose ground wire on the transmission. I replaced it and I have had ZERO problems all day.
