i have a b18b obd1 integra. i installed a skunk2 intake manifold on it and having problems. it seems to blow alot of white smoke all the time i think its coolant. and i drive down the road when the thing is cold and it works normal (still with smoke though) but when it gets warmed up theres more white smoke and it is bogging down almost to the point its not driveable and kinda sounds like it is running on 3 cylinders. would it be that i reused my old intake manifold gasket i no its a bad mistake but i needed the car.
second problem i have is that when at idle (warm and cold) the rpm's go from 1200 to 2500 up and down all the time.

- ok put new gasket on tonight and still same problem

 

NEVER REUSE A GASKET! I think your problem speaks for itself. There only like $15 how big of a bind could you of been in to cheap out on a gasket?

 

sure enough going to get one today

 

well i got a gasket and put it on tonight but still the same thing sounds like a 3 cyl. i don't get it spark plugs farely new took em out cleaned them too.

 

if you think its running on 3 cylinders then you got to figure out witch one isn't running. to do that you need to check your spark or when it is running just pull the spark plug boot out one at a time to see if you have a difference in the way the motor runs. if no change in any of them then there shouldn't be a miss. make sure your coolant is full or the iac is working properly. they can cause an idle problem.

 

yeah last night i checked the spark and theres no difference in cyl. #1 (or if your looking at front of car its the one thats on the left side). its right beside the coolant line going in my intake manifold then into my motor on the left side i thought that was the problem. the one thing thats better is the car doesn't smoke white as much now. and yup i fixed the idle problm thanks i for got one the lines going into it.

 

try running new spark plugs

 

run a compression test just to get a better idea of your problem

 

ok i just got done doing a compession test it was 185 to 195 on the cylinders and bought new sparkeys still not working. im out of ideas

 

ok i found the problem ends up that 2 of the needles off the tip on the injectors were broke when i put the new manifold on. luckly i have a b18b spare motor i took injectors off that and put the fuel rail back on and she started right up no troubles. it makes a noticeable amount of power too. well i lernt my leeson don't rush sh#t and do it right. thanks for the help
