I drive an automatic, 2000 Civic DX, I've owned it for a year, all stock from what I can tell except for an aftermarket exhaust. From what I know it was in a front end collision before I bought it. I've always had idling issues, there would be surging and a bit of a throttle lag. I've since done a small tuneup and replaced the spark plugs, distributor cap, and fuel filter. I plan to do a timing belt/water pump replacement soon because I can tell the belt is very worn. Somewhat recently I had been experiencing a complete engine stall, occurring usually when the AC was on but it stalled when the AC was off as well. The engine would sputter and unless i pumped the gas continuously, it'd stall completely. I replaced the fuel pump and after that, the engine stalls stopped dramatically- but not completely. I had no CEL but I assumed since it was still idling funny anyway, maybe the IAC was going. A little while later a CEL popped up and threw a P0505 code so I replaced the IAC. Yesterday I drove all over with the AC on no problems, though i have noticed there seems to be an increasing throttle lag. Today I was driving with the AC on and the engine stalled. I turned the car off and back on to reset the computer, the car kinda misfired a lot and the engine stalled again. It took a few restarts to get driving again. If i would stop at a light, it'd stall. It almost felt like I had to keep the RPM's at a certain point to prevent a stall. I kept the AC off because that seemed to make things worse, if I idle with the AC on the car would misfire a lot. I have also noticed an intermittent high-pitched squeaky noise on while driving, it seems to come from under the hood but I can't really tell in the driver's seat. The only other thing I can possibly think of right now is a vacuum leak but, with no CEL on at the moment to point to any specific cause, i'm running out of ideas.
Any input would be greatly appreciated.
