1997 Civic HX jerking issue

[Goodi]

Hello everyone, i am new to the site so please bear with me on this,

Okay so down to the issue at hand, i just bought a 1997 civic hx 5-speed manual, it drives nice and whatnot, but when i give it gas in ANY gear, or let off the gas in ANY gear it jerks/sputters. It's kind of hard to explain without driving it for yourself, ive been told it's a number of things (vacuum leak, IACV valve, IACV motor)

So im very confused on which issue it is, but i got the code read and it read a code P0505, that means it's most likely the issue. I just thought i woud jump on here and get some opinions/advice.

Clean the IACV and then go from there.

UPDATE - Well i cleaned the IACV, helped for about 2 hours. Engine light back on, time for a new idle control motor?

It's uncommon for the IACV to go bad. Are you having idle speed problems? High idle, low idle, or hunting idle?

 

[Goodi]

It'll idle from 1,600 RPM, then go to 800. It'll keep doing that until i turn the A/C on, then it quits.

Was P0505 thrown again, or a new code?

Try adjusting the idle speed as per the service manual instructions for your engine - see site 1 in my signature.

Got the IACV cleaned, and timing belt replaced (was already cracked and lost its tension) And the idle is perfect. It does idle to 3-500 tho,(It's not a fluttering idle, it's steady one) not sure it's a big deal but rather safe than sorry i suppose.

Now there is a strange knock in the left front wheel (control arm? Bushings?) Who knows, gotta get it checked out.
