1g: Car hesitates on start up...Bad MAF?

[sliver]

My car sounds like it's about to die on start up. It happened out of the blue. Overnight.

I checked spark plugs, got spark from wires, did compression test, and so on. But when I unplugged the MAS it still had the same hesitant idle. So I don't think it's a boost leak. We are going to check for vacuum leaks and such tomorrow but overnight? IDK, help?

just bought new temp sensor.... glad i didn't just put it right in because the female is different size . Ive looked everywhere and I'm positive i know where the CTS goes and is located, has a white plastic slide for it and everything,,,the one i bought is black , everything online looks the same as what i bought ... I didn't see any that look the same as mine.... any ideas?

Vato zone has sold me the wrong one time n time again... just make sure you have the right sensor... you want #5 and sounds like you got the ac switch #6

i was still running the stock EGR and had the EGR valve get blocked up and it would not fully open or fully close. this causes a vacuum/boost leak that is very difficult to track down. if you try all the common stuff and still have what feels like running rich and or odd intake leak pull the EGR and plate it closed. i tried unhooking mine and due to how it was blocked up i could not get it to close or open using the ports, air compressor, vacuum pump, etc. so i had to disconnect it and put a block off plate in between it and the head.
