When it's cold out, my Loyale doesn't not like to idle. I have to sit there and rev it at 2000 RPM for at least five minutes before it can idle at 500 RPM. Then, as I'm driving, whenever I push the clutch in, the RPMs fall so fast, the car can die. I must feather the throttle to keep the engine going (very hard to do when braking). After about 10-15 minutes of driving, a "switch" flips in the engine and it idles normally. If I let the car sit for more than four hours, it goes back to "cold mode" and I have to rev it until I can get going again.
Here's a list of thing I've done to the car (although some might not apply):
-Swapped out IACV with a junkyard one
-Cleaned the junkyard IACV
-Swapped out coolant temp sensor with a junkyard one
-Swapped out CTS with a brand new one
-Swapped out PCV valve with a genuine, OEM, brand new, dealership one.
-Swapped out fuel filter with a new WIX filter
So really, I'm lost. Search results come up with IACV and CTS, but nothing more. Oh, and just to answer any potential questions, the temp gauge inside the car reads fine. It rises above the "C" after 2-5 minutes and stays between 1/3 and 1/2 of the way. Do you guys have any other ideas for this?
I have a used/junkyard mass air flow sensor in my garage. Gonna probably swap it out tomorrow and see if that helps. Other than that, the next thing I am going to look towards is my fuel system and exhaust system. My exhaust system is two years old. Bought the car a year ago, and have receipts for exhaust work from the year before. Not sure how long exhaust systems last though. I have no idea with the condition of the fuel system.
What are your guys' opinions? It looks like future repairs are gonna run me a bunch of money, so I want to get a solid opinion towards a solution before I start dishing out cash. I'm also going to the junkyard on Sunday, so anything I should pull off the cars that are there? Thanks.
