[Cr-v trouble]

I had codes 1077/1078. Cleaned then replaced imrc. Began throwing 0505/1505 so checked leaks with carb cleaner, cleaned throttle body & iacv, changed pcv then got 1129 code. Changed iacv, worked for 120 miles but code is back. I'm stumoed.

This is why it's best to have a mechanic sort it out. You likely not have a leak around the intake after replacing the IMRC. One of the vacuum lines, intake gaskets etc. Something is leaking.

Be helpful if people would post what the codes mean because not even mechanics have the 1000s of codes memorized.

Check TPS and use a scanner not just a code reader

I cleaned my egr ports and throttle body last week and my 650 idle then shot up to 900, with random surging of up to 1700 idle while slowing down. My crv threw the p507 code, idle speed too high. I tried relearning the idle speed, cleared the code but it did no good and the idle stayed high and kept fluctuating. I did some researching and learned that I needed to do the two tps reset procedures, with a bi-directional scanner, to solve that surging and high idle problem. I read that this reset has to be done after any cleaning or replacing of the tps or idle control valve. I purchased a scanned that is capable of doing that reset and much more, did the tps reset and my idle and driveability problems were then solved. I got my info from a post on this forum, regarding tps and idle relearn procedures.
