Default Car acting up

Well, hello. I bought my car 2 months ago and since I have done some service stuff, change all 3 motor oil, tranny and diff oil. I have a couple of things going on recently that wasnt there before. The car in question is a MY03 with 75k miles on the clock, daily driven now.

1. Since buying the car, I have notice the tranny/diff whinning. I recently did the output shaft bearings but it is still whinning after 30miles per hour, increasing with speed and getting worse at around 60. Now, after the work done, Im having every clutch slave pin symptoms. Clutch got changed with a brand new OEM Honda before I got the car and it was working just fine. Also, the shift linkage sounds pretty loud when turning with the clutch pressed all the way.

2. Car does the typical heat bog after a while driving it but now is getting worse with the AC turned on. When my mechanic initially checked the car, he noticed a loose sensor on the throttle body (cant remember which one right now. Im betting the one by the side since the top one still has the rivets) and the car had a pretty bad rev hang holding the revs up to 2,500rpm until fully stopped. He correct the issue and now the car is running good, with still a little of a rev hang but only 1,200rpm and quickly drop to a 1k rpm when stopped. Now with that idle rpm, the car drops to 7-800 when the AC compressor engage, making it hard to drive out of a hill without revving it up.

3. The car has no secondary air pump and has no CEL other than the O2 sensor that should be on the cat. My car has a test pipe instead and I need to do the mechanical fix soon so I can clear the dash from any CEL. Im assuming it has the relay for the pump to fix the CEL but cant find it.

I just need some insights in repairs or check stuff before I send it back again to my mechanic. Any information or ideas would be great.

Thanks in advance.
Carlos

Multiple, unrelated issues. Car prolly needs good looking over, in person.

Good luck with your mechanic.

This is exactly why I dont believe in garage cars that get driven only once a month or so. If something is gonna break, just make sure that is getting broken using the damn car. Now Im sure, using the car as a daily, got all the issues that "werent there before". Well, Im guessing Im sending back the car to the mechanic. Adding to that list, today got the TCT ticking for the 1st time. Just for a second but twice at idle after warm starting it.

The chain tensioner needs oil pressure to work. Takes a second or two, if car has been sitting for awhile. Another good reason to use quality 0W-30 or 5W-30 oil. Flows sooner, when engine is cold.

Well, Ill check the level tomorrow just in case, but oil got changed 1k miles ago using Mobil 1 10w30 full synthetic. I live in PR where it is always hot. It doesnt burn any either.

Slow down and focus on each issue one by one. Which is most important to fix?

Checked the oil today and it is missing some when full cold. Ill go grab a quart and check again after letting it stand for a couple minutes. Ill refill as needed and hope this is the reason for the TCT.

I just want to be able to drive the car w/o thinking Im making any damage or anything, and thats exactly how I want to address the stuff, in order of priority.

Quien cambiar el clutch? Ellos usan el Honda urea grease? Porque usando el grease incorecto causen problemas cambiando gears con este carro. Si ellos no usan nigun grease es peor. Los clutch splines especialmente necesitan este grease.

Pero tu problema con ruido usando clutch pedal, este problemente es el clutch slave cylinder rod necesitan grease, y tambien a ser polish. Pueden poner este rod en su drill, y con un scuff pad, polish muy bien. Despues, poner mucho de urea grease. Hay un diy con fotos.
