Hi Guys. Great forum here. This is my first post so please bear with me. I recently aquired a '91 Accord EX with 145k miles on the motor. She runs great but the only problem is the throttle plate (hope that's the name) in the throttle body sometimes sticks (closed) to the point where I have to tap the gas pedal slightly to release it. I've tried woking the throttle linkage by hand and the same thing happens (sticking) I have force it open. The linkage isn't being obstructed by anything as far as I can see. Any ideas as to what I can do to fix this?

Thanks in advance.

 

Have you tried cleaning the gunk out of it?

I cleaned it with throttle body cleaner then wiped with a clean cloth but it's still the same.

 

are you absolutely sure its the throttle and not something hooking up the throttle cable or anything? if i were you i would check the throttle cable everywhere i could. good luck

I'm pretty sure it's not the cable hanging. I moved the throttle linkage by hand and it's the same (sticking). I have to use considerable effort to get it unstuck when manipulating the throttle linkage by hand.

Thinking back, I once messed with the idle screw on a Pontiac which was idling a bit high and the throttle plate started sticking a bit. I don't know if this applies to the Honda...but maybe the previous owner messed with the idle screw...who knows... The idle speed on the Honda is about 1,000 rpm when warm and in park and about 750 rpm when in drive and the breaks applied. Does this sound about right for the idle speed?

I appreciate all you guys replying.

 

the "warming up idle" seems a lil low, but the normal operating temp idle speed is perfect. you could still mess around with it a lil to see if it will do anything.

"Warming up idle" is actually about 1500rpm which eventually goes down to about 1000rpm when fully warmed up

Thanks for pointing out that oversight. The rpm eventually go down 1000 when fully warmed up. I've also edited the original post to reflect this.

 

are you guys sure?? on my 94 Lx, it warms up and drops to 750 on its own or 500... everytime i adjust the idle, eventually it goes right back to the 500 mark for some reason...

Are you hooking up a good tach, or going by the tach on the dash. (they aren't very accurate)

 

im going by tach on the car... who makes a good tach for precise adjustment? sorry for the thread jack
