the purge? on top of manifold is not pluged in. I have no codes besides vss. should i worry? there is a plug in the harness that fits the mani and the civic temp sensor. when i plug the temp sensor the car runs better.

help

can u be more descriptive on what your talking about

the civic ex has a temp sensor on the intake tube, integra doesn't. the integra has something on top of the intake manifold that looks like a purge, civic doesn't. the plug on the civic harness plugs into the the thing on top of the b18b manifold and the civic temp sensor. both are obd2 96ex and 99integra motor 96ex harness used.
as of now the thing on top of the b18b manifold is not plug into anything should it be?
should the intake temp sensor be pluged in?

yea...depending on the intake temp...the motor will add/subtract fuel and timing to avoid detonation

Having the IAT( intake air temp sensor) plugged does help the car run better and idle better to, as for the one top of the manifold, I would leave it plugged in because I think it helps with the emissions.just my two cents
