Problems with home-made intake?(semi-long)
I followed the instructions on how to make my own midpipe and HAI, and I put everything together properly making sure there were no leaks. However, it has been about a week since I installed it, and now my max has start-up and idle problems w/no CEL coming on. The start-up problem is this: whenever I start the car (after a few hours) the rpm goes up as normal then suddenly it drops down to ~450 rpm and slowly raises back to normal idle. That is when my idle problem occurs. At idle(~600-700rpm), the engine shakes some like it is either running rich or lean. The exhaust vapors seem to be the same during idle(no black smoke or sputtering), no CEL code, and I cleaned/protected all of my sensor connectors along my intake. The gas mileage has not suffered much, and It runs fine throughout acceleration, but I do not want this seemingly small issue turn into a financial crisis. thanks for any help/replies

Did you use a breather filter? A few people reported such problems and the associated it with the breather filter, I don't know why but they did. I use a breather filter and it caused to such promlems.
You may have a leak you don't realize or it could be caused by something totally different. Dirty TB, PCV valve, TPS,......

I used a breather filter for the hose coming from the valve cover. I have not checked my PCV, but I have cleaned my TB and IAC fairly recently(last 400 miles). I sealed questionable areas with silicone. I didn't hear about people having problems w/their breather filters, I tried to search for "custom intake problems," but maybe there is a better phrase that I could use. thanks for the reply

The idle problem also occurs at stop lights and such, thanks.

Actually,
I changed my oil about 800 miles ago, used the correct filter, and cleaned my TB and IACV about 400 miles ago. I always use 93 octane (chevron or shell), and I used a fuel system cleaner at the oil change. This problem did not begin until I installed the intake pieces.

Thanks for the replies. My idle has slowly gotten better on its own(?), but it's still not 100%. And I only used a breather filter on my "crank case." thanks again, peace
