    I went out and started my car this morning and let it warm up And then took it for a spin. It felt perfectly fine today but still am putting new plugs in once my tools are back at my house. I'm hoping the IACV isn't bad seeing how expensive it is...

    So after swappig out the old plugs, previous owner clearly did not care about maintenance seeing how they were the stock plugs with 130k on them, the car runs like a top. The only catch is that it still idles a bit rough at times. When I took off the IACV to clean it I noticed that the throttle body was just as dirty as it was, would you recommend taking the TB off and thoroughly cleaning it and possible clear up this rough idle. It only idles rough when it is warmed up and it sits at around 500rpms +/- 50 and drops down to as low as 250 rpms and jumps back up. It is not vigorous and when it does do this it only happens every ten seconds or so. No CELs are currently present and I'm oping it will stU that way. My apologies for the late response but I've been crazy busy, thank you for all the help!

    I figured the plugs were a problem.

    What about other items such as the air filter? I'd go through and do a basic maintenance check on everything. Also clean your MAF and run a few bottles of fuel system cleaner through it.

    Replaced the air filter last week and I've been running techtron through the fuel system periodically since I got it, that and seafoam. The plugs had almost no electrodes left and looked absolutely horrible. MAF has been cleaned every other week since day one of having the car but now that I got the car performing much better, other than idle, I took it for a tiny "rally run" and went through a puddle completely forgetting that I have a CAI and think I sucked some water up and births maf with it. Everytime I get into full boost it sounds like I'm "two stepping" until I let off, so basically for a second. Once im home um gonna make a shield for the bottom of where the filter sits and clean the maf sensor. Thank you for the help.
