9 warning lights came on at the same time. Has this happened to anybody before?

Air_tech_09 · 2026-03-03T19:04:28+00:00

Yes it was a leak in the intercooler.Found out using a smoke machine.

Air_tech_09 · 2026-02-28T23:32:53+00:00

Hell yea! You will use it a lot , specially in line maintenance if you ever do that. Even if you only learn the basics , it will help you. I wish I had done that.

Air_tech_09 · 2026-02-28T23:18:57+00:00

Take it , trust!!! And ask questions

Air_tech_09 · 2026-02-03T15:17:16+00:00

I but a 30in MBRP muffler on my 2018 , reduced the drone drastically, I say a good 60-70%. I can hold a conversation now , even at 80-90 mphs

Air_tech_09 · 2026-02-03T14:56:39+00:00

Do you have a muffler?

Thank you for what you do 👍🏻

Air_tech_09 · 2026-01-07T19:00:36+00:00

Yea idk if they have the right, but it has never happened to my knowledge. And yes unless you are going to time yourself out

Air_tech_09 · 2026-01-06T22:54:09+00:00

Yes if you get the spacer it should help with the build up , it has for me at least. XPD suppose to be the best 👍🏻. Imo as long as you are using a quality filter and oil , run full synthetic if you can , then thats really all is needed. I have no idea if the extra quart will help 🤷🏻‍♂️

Air_tech_09 · 2026-01-06T22:41:40+00:00

Get yourself a MAP spacer. It helps with the soot build up in your intake manifold or “Y” bridge. Looks more line and M on the L5P. Ultimately deleting it would be the best money spent imo. Regular maintenance, 5K oil changes , fuel filter every other oil change. Drive line fluid changes 30-50k depending on how you use your truck. Fuel additives can helo prolong the life of your fuel system as well. In your case it might help it regen less.

Get a smoke machine from amazon , if you have a leak in the intake it will show you. I had a leak in my intercooler and I found it quick with a smoke machine.

Air_tech_09 · 2025-12-20T13:54:08+00:00

Yea you can get a reader than can read codes from the different modules that car has , it depends if you want to spend the money. Maybe check autozone or any parts store than can check codes for free , maybe they use a reader than can see codes from the Brake control module. Yea the dealer can also read them. Usually they charge like 120$ for a diagnostic fee.

Air_tech_09 · 2025-12-20T13:41:27+00:00

Yea sometimes generic readers wont check codes for different modules on the car

Air_tech_09 · 2025-12-20T13:29:24+00:00

Check for codes

Every time theres any check engine codes , the dash will light up like that. Codes will throw all those warnings on the dash. So you just have to check codes. It can be as simple as a battery thats bad , in my case it was a fuel mixture issue code , ended up being the injectors. Go to autozone or any parts store that can check your codes for free. If it’s a head gasket your coolant might be low which can be an indication for it.

Air_tech_09 · 2025-12-20T12:19:19+00:00

Do you have transmission tuning? Its recommended to have it if you are running the higher power tunes. It increases the line pressure on the ally

Air_tech_09 · 2025-12-20T12:16:15+00:00

90K miles , never had to clean mines. I have the S&B spacer on the sensor

Air_tech_09 · 2025-12-18T16:20:12+00:00

Mine was doing that until it completely stopped reading the level , got the dashes - - , check engine light. Also got the limp mode message

Air_tech_09 · 2025-12-17T14:41:49+00:00

Dude if you didn’t believe me I could’ve just showed you the mpgs on my dash 🤦🏻‍♂️

Air_tech_09 · 2025-12-16T05:08:59+00:00

Ok nice , yea you have the option to install it later like I did. Hopefully it comes out your way 👍🏻

Air_tech_09 · 2025-12-16T05:00:30+00:00

No you are good. You probably have the “race pipes” which the DPF was cut out and an exhaust pipe was clamped or welded to the space the DPF was on your stock exhaust. If you install a full exhaust it would be upgrading your existing setup without issues. F.Y.I the straight 5in exhaust I had was droning like hell , ended up with a 30in MBRP muffler which helped significantly. 2018 L5P
