Default Erratic Idle & Miss

Hello All:

New to the group, but not Hondas .

I have a '93 Accord EX that has lost 25% of its gas mileage and has a
varying idle when in park or neutral. I've replaced the spark plugs, and
ignition coil (because it ohmed bad) but the problem is still there. I
suspect it might be vacuum hoses.

I also read the EGR (Engine Gas Return) causes bad gas mileage. I'm thinking
of replacing all of the vacuum hoses as this car still has the OEM hoses
with over 160K miles.

Any suggestions on a remedy or where I can get a complete set of OEM hoses
would be greatly appreciated.

Thanks!!

How many miles and years are on the PCV valve?

A malfunctioning PCV valve may cause the gas mileage to decrease significantly.

Could be bad plug wires,or worn distributor cap.

Thanks for your suggestions.

I replaced the PCV valve about 2 months ago. I've thought of replacing the
distributor and wires next, but wanted some input before I spend the money.

I also jiggled the vacuum hoses and it seemed to temporarily fix the high
and erratic idle. I drove the car today and it's back.

I'm afraid of replacing everything and spending $$ on things I may not need.
But I do believe I will buy new wires and distributor cap & rotor.

Thanks again!

If wiggling the vacuum hoses temporarily fixed it, you found your problem.
You have a vacuum leak. Replace the old hoses and look carefully for cracks
in the mounting points for the hoses.

That's what I thought. I called around to see if the hoses are sold in a
kit: I've been told no (at least by the parts stores). I read in the manual
you must be careful about replacing the hoses due to certain thicknesses and
pressures. That's why I was hoping there would be a kit.

Any ideas? Or can I just use basic rubber hoses sold by the foot at the
parts stores? I like the OE hoses as they are numbered which matches the
repair book I purchased.

Any insight or help would be greatly appreciated.

Thanks everyone!
