i purchased a 1990 integra for low $$$. the motor in the car is a b16a2 (motor is okay, but not perfect). not trying to build this motor or anything, just want it to run normally till i get a new motor.

an illustration (crudeness absolutely forgiven) on how this vacuum line setup should work would be really appreciated. i've looked all through archived stuff and can't seem to find anything DA related on b16a2 vacuum stuff

i'm thinking tps sensor, timing maybe since it's the ls distributor with only 2 bolts holding it on, and of course vacuum.

the car ran home as he had it connected with a lobed idle and throwing a code 43 (fuel).

the only way i could get the car running since was by removing the line to the air boost valve, the purge cut solenoid, and regulator control solenoid valve. still it only runs for approx. 10 seconds and dies. ecu codes 3 and 5 (map), and code 7 (tps), no code 43 anymore...

it's running the ls pr4 ecu, ls distributor, and ls injectors with an s80 tranny.
the oil pressure switch is damaged (shouldn't matter till i put in the pw0 ecu and run the wires for vtec?)

really, i've been looking around since last friday before i posted b/c i didn't want someone just telling me to search. i've looked all over. i even searched the "let's cut down on engine swap q's" post but can't find anything on B16 into a DA.

i understand for swap purposes B18, B16, etc, are somewhat interchangeable on the big stuff, but i need vacuum hoses on a B16A2 running OBD0 in a 1990 teg.

thanks ahead of time for any help!
these are the connections i need to know (circled). pardon my drawing:
if you want to submit your ideas...
open this pic in mspaint or whatever and draw the vacuum lines in with red and try to cross lines at right angles

this is what i found, but i have 3 connections at the firewall rather than 2...

ILoveJDM.

Would love to help you man... I have a B16A in my DA, and I could use it in reference to yours... So your idle is jumping? Beforehand, have you checked the IACV, FITV etc.? If no, do so... I will check my firewall to see how many connections ive got...

i bought the car on friday the 12th and then it immediately thereafter jumped to 1-digit weather by me which put the halt on diagnostics (it's been sitting in the garage). i will look into iacv, fitv, and i'm buying a tps sensor "just in case" since i actually have boltends on my TB to take the old one off.

it runs with the vacuum hooked up as shown (no intake tube)
sorry the pics are a little blurred

the 3 sensors on the firewall are shown here...the far right isn't used as it was the original map sensor and the previous owner broke off the plastic connection.

my map sensor is independant from the three and shown here...

thanks! quick test since it's late and it didn't throw a code, just idling a bit high till i can adjust it tomorrow.

i was running it without the intake tube for testing so rather than connect the airboost to pcv it can just get fresh air. i didn't draw the line to pcv b/c it's a larger diameter vacuum tube (i only needed the 1/8" info).

seriously, thanks. a lot of little things are needed fixing, it's just nice to have a baseline for comparison on the vacuum.
