car sputters, feels like dying after 10 sec of idling
Ok i have a 1995 integra ls automatic. this past weekend i did some work to it, and ive been getting better throttle response and it seems to have a little more "giddy up". here is what i have done:
Cleaned throttle body
cleaned fitv valve
put a breather filter on valve cover and plugged the hole in my SRI
I broke a bolt in the FITV, so i just bolted it back to the TB with 2 bolts and put it all back together, when i started it, my idle started surging and my exhaust seemed to get louder, and the fumes seem to smell alot stronger. The next decided to bypass the FITV because it had started leaking coolant anyway, so i put some gasket material between it and the TB and bolted it up with 3 new bolts and ran a coolant line straight to the IACV.
After i put everything back together, it of course idled rough while the engine was cold, but once it warmed up it still idles a little funky and hesitates a lil bit until i get on it. I went and replaced the plug wires with new NGK wires (i still had the stock ones on), and it started to run better but not quite 100%. The next day i put a new cap and rotor on, and couldnt get spark so upon further inspection the ignition coil was bad(also stock, reading 8.6 ohms, supposed to be 12.6-19.6k ohms). I replaced that and got it to start back up.
Now my question is, why did doing this cause my exhaust to be louder and sputter at times? Also the fumes smell alot stronger. I know my cat is clogged, and ill be replacing it shortly. And also, once my car warms up it will idle fine for about 10-15 secs, then the rpms will drop really low and almost stall, but the will start rising and falling until i get on the gas again.
Im thinking i need to clean the IACV, but does anyone else have any ideas?
