QuestionQUESTION: I have just noticed a sucking sound from the engine when I turn it off. It's a 91 Accord LX with 278k on it. It runs very well. Not recent problems. I baby the thing. I changed the air filter when I noticed it. Nothing. Can't seem to find a vac leak. Suggestions? Thanks in advance.
ANSWER: Hi Mark, something is loose and or disconnected under the hood. Or had you installed the air filter first? Then the problem occurred? If so, was it a K & N air filter? If not return the filter for a K & N and tell me if this problem still occurs. Let me know if this helps...

ANSWER: Hi Mark, I have noticed that the K & N filter will produce a sucking sound whether it is in the stock replacement form or intake style. Whichever it is a good replacement to use especially with your car at 278K+...

QUESTION: I have traced the sound to the throttle body sucking air thru the air intake tube. Suggestions? Thanks. Mark
AnswerMark, you might want to consider replacing the Throttle Body sometime soon. Inspect all hoses/vacuum lines going in or around the Throttle body area. Even the tiniest crack can cause this issue as well. Replace all damaged hoses. There is a gasket between the Throttle body and Intake itself that could be leaking/sucking air as well. This is cheap and is easy to do yourself. Let me know if this helps...
