i own a 93 civic lx i swaped in my a6 because the old d15b7 blew. i changed the timing belt, belt tensioner, water pump, cap n rotor and some ngk's. engine started but it idles pretty damn bad.. 1k rpms to 3k and it keeps going up an down. i hear a clicking sound when the engine is running,. i checked the compression an it reads 145 145 145 150. any suggestions would be appreciated

 

check for major vaccum leaks. pull of your iacv and clean it out with brake/carb cleaner. the engine's old so you should probably replace the seal in there too. its only about $4 at any honda/acura dealer.

 

thats the first thing that im going to check in the morning. anything else that i could check for? i put everything together like it was before and its not even throwing any CEL codes

 

compression seems to be a little low, I would double check the timing. Also check for vacuum leaks and fitv performance.

 

the a6 doesnt have a fitv lol. as far as compression readings. how many revolutions did you crank it over. i believe you're supposed to do it about 5-7 times. if you did so less than 5 full revolutions that may explain why the reading is low.

 

oops my bad, did not know. just know that every time I hear about a bouncing idle, that is usually the culprit

 

i did crank it more than 5-7 times and it still reads 150 all across. but would torquing the head more raise the compression in the cylinders? i changed the headgasket and torqued it down to 45ft pounds

 

I am not sure what the a6 is for but if it is a b16 then the torque on the head should have been in two steps 1. 22ftlbs 2. 61ftlbs. it could be that the head is not all the way torque down. hopefully nothing was warped by driving it with the head not all the way down. that is if it is a b16. if it was a d16z6 then it would have been 1.22ftlbs 2. 53ftlbs.

 

im going to check if theres any vacuum leaks with a vacuum pump and torque down the head to 55ft and hopefully it resolves the problem

 

theres no vacum leaks anywhere. whats the compression supose to be at above 160psi through out the cylinders?

 

should be around 190. trq sequence for the d16a6 is as follows

Tighten cylinder head bolts in four steps in the sequence shown:
1) Tighten all 10 bolts to 20 Nm (14 lb-ft)
2) Tighten all 10 bolts to 49 Nm (36 lb-ft)
3)Tighten all 10 bolts to 67 Nm (49 lb-ft)
4) Tighten bolts 1 & 2 to 67 Nm (49 lb-ft)

 

did you have the trottle all the way open when you did the compression check?

 

i retorqued the head to 55tq while it was hot. the firing order is right and compression test reads 165 200 165 165. i checked the spark plugs and cylinders 2,3 are oily and others are white. car is running on 2 cylinders and i dont know why middle cylinders are not firing on time. any suggestions?

evening bumpp

 

Did you adjust the valve lash?..if you didn't that can explain a lot.
Set the valve lash and retry,I'll bet it helps...I am saying this because you stated you heard a clicking noise..hope that helps ya.

 

ill adjust tha valves in the morning an see if it helps anything. is there a order on how to plug the injector wires on the right way?

 

have you cleaned the iacv?

 

yeah i cleaned it with that carb shyt. is there any other reason why cylinders 2 and 3 would be firing at the wrong time? ecu maybe?

 

do you have the distributor wires right>?

 

you said you torqued it to 45, so you didn't follow the proper torque order?

yea check the wires. it's real easy to get them mixed up if your not careful.
