Could this cause a car struggling to stay started on a cold start? I noticed after checking my MAS it was completely black in which i could not get rid of the Residue when spraying it. Once my car has started warming up the idle smooths out with no issues after through out driving the car. I have no check engine lights nor codes. I’m totally confused as to what the issue is. I also change the spark plugs.

@zealgaming9123 2 жыл бұрын

I don’t have a check engine light on but I recently checked my cabin air filter and it was really dirty with leaves and debris… the next thing it effects is the MAS correct?

Always enjoy your presentations. The ECU and details on how its works would be appreciated. Do they come from one or two manufacturers, then just programmed to the car company specs? What do you offer in terms of getting the live data out and examples of this. What do you think the 2020 and 2021 scanners models are going to evolve to?

You are absolutely amazing! Thank you for the great enthusiastic, upbeat, and thorough lesson. Was going to use vinegar in a spray bottle to clean the sensor. So happy I looked into this first. One question. Can't seem to find how to clean the fixed filter in a 2004 Lexus RX 330. Do I have to replace the whole filter housing? The inside is full of, what appears to be, nesting material. It is my mother's car and it only sat for 2 months, intact. We replaced all of the coil packs and spark plugs. Codes read 5th coil pack malfunction. When we were ready to replace the housing and new filter, we noticed the fixed filter on top. Then noticed the sensor definitely needed cleaning. And the inside is nasty.
