I am starting to think that too since I get so,many issues with its response once the lights are on. I made the mistake of not using an oe maf, do you think that could cause it?

I think I will order one, I saw the Hyundai one on Ebay for around $169 the other day. Not exactly sure what I was thinking when I went non OEM.

You can confirm its the maf by disconnecting it. If car runs fine then thats the problem. Have you had valve cover oil leak recently? Can you see sn signs of an oil leak in the past?

I am now throwing P0172 and P0175 codes in addition to the P1500. It seems they are usually caused by a bad MAF. The new OE MAF wil be here on Tuesday and suspension plus axles wil go in Saturday. Hopefully this takes care of the issues. If not I might have a smoke test done just to eliminate the possibility of a leak somewhere. When the car is cold it runs perfect but once it warms up the lights come on.

The car actually runs fine for around the first 15 to 20 minutes of driving, then once the EML, ABS, Traction, Brake lights come on, the issues start. Once those are on, there is reduced power and the car doesnt want to downshift when accelerating.

The valve cover gasket is brand new, there are no signs of leaks anywhere either. New MAF will be here tomorrow, hoping it helps!

New MAF is in, so far no lights, but only drove around 10 miles. Will drive more later.

Koni/Eibachs are sitting in boxes just waiting to install.

So the MAF did the trick, no more lights and the car is running perfect! Amazed the MAF could cause so many issues, I would say the OE MAF is the only way to go on these cars.

Thanks for the help everyone!
