I recently droped a lsvtec in my 88 crx HF and i am having a few problems. First the B18A block has a temp sensor on the back and the gsr head has one on the waterneck. what one do i use??? i tried useing the search but cant find anything. Second the motor idles at about 4k. I cant find a vacuum leak and i am totaly lost. please help.

 

i gotta get this on the road... please help!

 

i would use the one on back on the block.is the temp sensor on the water neck before or after the thremostate?

 

i dont think temp sender is any problem, use any one will work,, ok,
check the vaccume to break boosteer if its working ok,

 

who cares it is prolly only gonna run for like 6 months or so

 

Don't post if your not going to help or try to.
I'd use the temp sender near the waterneck, just because its easier to reach.
Spray some engine starter fluid around the manifold, if the idle goes up you have a vacuum leak, make sure the tb is closing all the way, also check to make sure you are using the right ecu and you dont have any sensors switched.

get the expletive out

 

Use the temperature sensor that goes with your harness so you dont have to cut anything. Your harness probably has it for the one in the back of the block. It should be two wires that are inside a big plastic boot. I believe one wire is black and the other one is yellow with a green stripe.

As for the vacuum leak. Try getting a vacuum gauge and check the vacuum.

wow?

anyway, i do see one problem. in the pic that you provided the hose coming off the valve cover is going to the wrong place. you have it going into the intake mani. the nipple on the intake mani is the port for the pcv valve. if you don't have a pcv valve in the system it will idle high. the nipple coming off the vavle cover needs to run to the intake "arm". am i making sence. try and see if that works

you should go to autozone and buy a cap. then cap that nipple and see if it helps. its def. hooked up wrong
