1998 Acura 1.6 EL , having idle issues
Hi...Canadian car, luxury civic basically.
The car has been sitting for over 1 year with a full tank of gas
182,00 KM, driven easy.
IM having some real issues with the idle. It will be pretty normal up untill the car is at optimum temperture and then the idle revs up and down frantically( 1000 RPM to 1600). Also if the gas is accelerated at just a very light touch the revs become pulsating like.
Drives perfect at speeds above 30 MPH
IM thinking, throttle body, TPS, fuel pump or gas filter.
I have dropped a little Methal hydrate ito the gas tank and sprayed some carb out into the throttle body. Checked connections to TPS and MAP sensor, and put new gas in it, however only a little as it was almost full.
Check engine light is on and will try to get the code for that tomorrow.
Any ideas ?
Thank you
John

Go out and buy a can of "Deep Creep" its basically SeaFoam in a spray bomb. That stuff is pretty amazing for cleaning throttle bodies. While you're at it, clean out all the sensors attached to the TB as well. That's a good start right there.
In the DIY section, there is a post about how to use seafoam in your car. Follow that, but in this case I would buy 2 cans of Sea Foam. Run one through the throttle body using the tube of your fuel regulator, the other can goes into the tank.
And even though the DIY post says it, please do it at night, or away from people. Your car WILL SMOKE LIKE CRAZY!

Also, pics of the elusive 1.6 EL? I really want one of those valve covers but can never find them.

I suppose I better take off the throttle body to get at it?
Thanks!
Gonna get on it after another coffee

Thanks for the reply!
Could I just shoot the Seafoam through the air-in-take of the throttle body?
When cleaning the sensors should I use a product or just clean the contacts?
Thanks

code 02
Hi Ron
Yes and the code was 14 if I remember correctly/idle control
Swaped out the throttle body for another(wreck) and still had the same problem. Well I had mine out I gave it a good cleaning including the idlle control valve. Reinstalled but no luck.
Going to try thermostat next.
Tried Seafoam too.
The tranny shifts up and down perfectly(auto) so I don't suspect a solonoid problem??
Idle still runs high and revs up and down constantly on about a 2 second cycle. When cold it idles pretty normal
Anybody got any ideas??
Thanks

The thermostat shouldn't have any bearing on the idle.
Did you physically remove the IACV and clean all the passages? Here is a DIY: https://www.hondacivicforum.com/foru...ad.php?t=62836
