post maintenance issues, my mr2, but 5s nonetheless Options

Okay, if you've been following my OT thread then great. If not, let me give you a rundown. So I yanked my motor and replaced a handful of crap. Oil pump seal, water pump, timing belt, accessory belts, clutch, etc.

After driving for a few days I have compiled a list of things I have noticed. I'm hoping some of the knowledgeable 5s guys can help shed some light.


1. Idle was 750 before the work, now its at 1250. No vacuum lines were touched. I did the propane test and found nothing. I adjusted the TPS and found nothing.

2. When sitting at idle it sounds like a belt is too tight. I'm going to loosen/remove the AC belt today and see if it corrects it. The sound is almost like the car is surging, but the Rpm's stay constant. Like I can hear the belt making a full rotation.

3. When in neutral at idle there is a high pitch squeaking noise coming from the engine bay. When I lightly press my foot to the clutch pedal (not disengaged, moving maybe 1/2") it goes away. The last thing I want to do is take it all back out to replace the throwout bearing. Anyone have any ideas?

New bearing. The sound seems to come and go. I had it idling in my driveway and it wasn't squeaking, so I tapped the clutch and it started up.


I tried adjusting the clutch push rod to see if I can negate it, but no luck.

I also found that my intake temp sensor wasn't plugged in fully. Plugged that back in and it dropped my idle down to 1000.... 250 more to go. I'll check my timing with a timing light in a couple days.
