So I had a code 1231 so I replaced my TPS with a new one. Now I experience something strange - when I am not stepping on gas, the rpm will maintain at 1.5krpm (used to be ~800rpm). When I pop the hood while the engine is running, I check the throttle body and the flap is closed. The cables are not tight and I don't see why it's thinking I have partial throttle. Check engine light for sure is on, and this time it's 1222.
I push up the throttle body arm (the one with hook at the end) a bit (it's already close so I can't push much...maybe 1/10 of 1mm?), and the rpm drops back to ~800. I think the new TPS is problem here. Any one thinks the same? Or could it be that my return springs on throttle is not tight?
A side question - is the hook on the throttle body arm suppose to hook up to some sort of return spring? However, I checked realoem but I can't find anything about this...any idea?
