#308961 I replaced the one in front right below dizzy with 2 plugs coming off I know the one behind it is for the gauge and its reading and i swapped it out with a spare one i had and the reading didn't change. Then I also replaced the one on the thermostat housing as well.

All of the readings on the cyl was in the 160's range if you need exact numbers i will have to retest again I didn't write them down.. so lmk if you guys want those. I double checked the wiring and everything seems ok.

I know im reaching at this point but my logic is saying small leak im really thinking about replacing all the smaller coolant hoses on the engine just to see if that makes a difference even though we did not get any loss of pressure or hissing noise when we did the pressure test on the system. I also have a spare radiator that I may swap out as well.

I know just switching parts isn't the way to fix the problem but as said before im having to refill my overflow container about once every 3 weeks im not getting any kind of smoke and when i get on the gas i don't have bad throttle response, my oil isn't milky looking i had a car before that was burning coolant so i know the signs of that.

Only issues ive had with the car assides from the check engine light is at times my idle is kind of crazy. when it gets warmed up i get idle surge but only in a blue moon. I know that has something to do with the iacv and I have a spare one of those I can swap out tomorrow as well.

#308962 He said hes switched all three; the ECT, the temp sensder and the fan switch.


Im betting its a wiring issue... even though I believe he said hes ran jumper wires.

#308963 I did run jumper wires. im going to replace my minor hoses and see if that makes any difference if not I will go back to wiring. I got a spare non vtec harness from a parts car.

I am dropping in a h22 in a few more months once i get the rest of the parts I need so I may just rebuild a engine harness cause I plan on adding a mil spec plug on the firewall at that time anyway

Right but it looks like if his compression is 160 that is 30 psi off from factory and that is quite a bit lower than what it should. Now it causing the code that is beyond weird. The fan switch really would have nothing to do with the code but the the 2 wire connector on the head would, the only thing he should check now is that the connector has good terminals inside of it they might have fallen out or not making a good connection in which it would throw a code.

The only other things is to make sure that the coolant system was bleed out before he sealed it up. but if he is loosing coolant than the temp gauge is spiking then I would put money on head gasket or there is a hose with a leak in it that is allowing coolant to get out.
