Engine check light turned on?

Hi,

A lean fuel mixture can result from a few things. First and most commonly, a damaged or disconnected engine vacuum hose. Also, a weak fuel pump can cause it. Additionally, if there is an exhaust leak before the catalytic converter, that can cause it.

So, let's start by checking for vacuum leaks first. Here is a link that explains how to do it. Let me know if you find any issues or if you have other questions.,

Hello Joe!

Thanks for your help! I checked if there's any leak and fortunately everything is okay, but sometime ago before that light went on I've tried to clean engine intake filter and after 6 days light was on so I thought maybe I caused it and I've ordered a new filter and after I replaced it ,there was no light since day 2 so I solved that problem!

But I have another one with the A/C, my A/C is working okay when it's rainy and not high temperature but when I'm outside there's sun (I'm in Florida so it's hell 24/7) my A/C can't cool enough the interior of a car.
I bought AC Pro 134a Refrigerant because I thought it was a low Freon but when I put gauge on a low-pressure port it shows 51 PSI (when my car is running) so, it's charged and there pressure but it's not cooling at all (in hot weather).
Compressor clutch is engaging. What steps Can I take to improve my A/C?
Thank you.
Have a great day.

Hi,

I have to ask a favor. We try to keep the threads specific to one topic, so they are more helpful to others. Could you start a new thread with the AC question? Just copy and paste your question. Here is the link to start a new post. I truly hope you understand.

Again, I hope you understand. Also, I'm in PA and I swear I live in FL. The humidity and heat are getting a bit crazy. LOL

Take care,

Joe
