After starting my car the other afternoon it started to run funky. When I start it cold it does fine until it starts getting to around 950rpms it will start missing, check engine just came on(getting it checked later) but I hear a whistle noise that sounds to be coming from inside the plenum. Any ideas?
Car did perfect that morning not sure what threw it off.
Just wanted to get an idea before I check my codes later today.

get the codes and do the usual visual inspection under hood- clamp loose- hose off- something broken

remember: codes are CLUES not a diagnosis in themselves.
Need to combine codes plus symptoms plus experience of members here to get
more than just a diagnosis = the real fix!

Work done on the car recently? always suspect last work done on the car!

Hey 01tl4tl! Thanks for the reply! Well hell on my way to get codes read the darn engine light went off, all seems well so far all the sudden. Maybe I need to clean the iacv... As I already cleaned the egr ports

Maybe it wasnt use to the weather lol it did it mainly when it dipped under 75 degrees outside

Another update, ended up going to the old shop I worked at and used a badass snapon computer scanner and it read p0132 which is a o2 sensor bank 1 high voltage

Any idea what the issue with that could be?

01tl4tl

that says front O2 sensor failure but never heard of one whistling
The other symptoms do point to it though
Use a DENSO brand- common to parts stores and the OE maker of the part so its total plug and paly, just reset ECU via CLOCK fuse removal for 1 minute

ck out the wires for the O2 ,its possible to damage them
How old are the spark plugs- correct NGK in there? EGR port cleaning inside intake manifold, and TB service with AICV cleaning?

car year, total miles and recent work done or needed = help us in diagnosing problems

It's an 02 TL-S when I was taking about the whistleing it is coming from the plenum it sounds like. But now that I think about it I had same code pop up about a year ago, I cleared it and it hasant come back since.

To be honest I have ngk g-power they are about 3 bucks a piece but I needed them in a pinch they are about a year and half old and have 25k miles on them

Cleaned egr ports but not valve. I want to clean the iacv but I dont have a seal. I think it was replaced before as the service history at dealer shows idle surging issue when it had 78k (now has 205k)
